Those are hardly specs, but I'm surprised Knoppix is only giving 640x480. Look in the "cheatcodes" file on the knoppix cd to find a cheatcode that forces X to other resolutions.

what do you mean? i thought the CPU/RAM/etc, would be useless to post

Well, the Intel Extreme Graphics Controller line has about a billion different chipsets. Can you post the proper parts of lspci as it relates to your graphics card?

This is what was in my CheatCodes:

NEW Kernels and Options in version 3.4:
knoppix26 [Options...] Boots with Kernel 2.6 (2.4 is default)
expert26 [Options...] Same for expert mode
knoppix26 acpi=off Disable ACPI configuration in Kernel 2.6
memtest Run memtest86 instead of Linux

Hint: Using the default DE-bootimage, SYSLINUX boots with german keyboard
layout. The '=' letter is located at Shift-0 on this keyboard (just in
case you want to change keyboard and language with lang=us).

*) Try "knoppix pci=irqmask=0x0e98" if (you have a notebook and) your
PS/2 mouse doesn't work. (Possibly caused by a BIOS-flaw on your board,
BIOS updates can help.) Sometimes, switching to the text console with
Control-Alt-F1 and back to the X-screen with Control-F5 solves the
problem without rebooting, since the X server reinitializes the mouse
driver during that procedure.

**)
You can also have your own splash-screen in putting an executable shell-
script to /cdrom/KNOPPIX/splash.sh. For an example how to do this see:
/usr/bin/splash-knoppix.sh. (Feature added by Fabian Franz.)

***) Bootfrom needs access to a running Knoppix-System with the same Kernel
as the Bootkernel, before it is able to mount the partition / ISO-Image.
This should allow a poor mans install from NTFS-Partitions and makes it
also possible to boot an ISO-Image directly. You can also use wildcards
in the ISO-Filename, but it must be unique. So: If you have just one
KNOPPIX.iso on /dev/hda1 you can access it as: bootfrom=/dev/hda1/K*.iso,
but if there are several, you need to make clear, which one you want.
(Feature added by Fabian Franz.)

If your KNOPPIX CD makes strange noises during boot, or you see
frequent errors like "cloop: read error", or programs on your KDE
desktop keep crashing randomly, then your CD image is probably defective
or incomplete, or your CD-burner created a defective CD due to wrong
writing speed or bad media. This is the most common error reported.
Please boot with "knoppix testcd" to check if the CD is OK, and/or even
better, verify the MD5 checksums that are present on the mirrors before
writing the CD. In some cases, defective IDE controllers cause this
error if you have DMA enabled. Also, please read the KNOPPIX-FAQ.

In case of a failing hardware autodetection, try booting with any of
the "no-" options as shown in the table above, like in
knoppix noagp noaudio noapm noapic acpi=off nodma nopcmcia noscsi nousb
to skip some critical parts of the autodetection system.

The "noswap" option is useful for a forensic analysis without touching
existing swap partitions.

Some Boards apparently don't pass the proper memory size to the
linux-kernel. It may cause the message "Panic: cannot mount root file
system" and the system hangs. Use "knoppix mem=128M" to solve that
problem if your system has 128MByte memory for example (caution:
you MUST use a capital "M" here).

The "expert" mode provides a very simple interface to loading additional
Kernel modules from floppy disks (ext2 or vfat), plus interactive
configuration of mouse/keyboard/soundcard/xserver. "expert" mode supports
the same boot options as "knoppix".

The "floppyconfig" or "(my)config=/dev/partition" options allow you to
reconfigure the system after autoconfiguration by running a bourne
shell script called "knoppix.sh" from the root directory on the given
device (or floppy). There is a GUI to create such a configuration
floppy disk calles "saveconfig" (also located in the KDE menu under
"KNOPPIX", but experts also know how to do this by creating their own
shellscripts. From Version 2.1 and up, a file called "knoppix.sh", if
located in the toplevel KNOPPIX directory on CD, will also be executed
at startup. This makes ist easier to create customized versions without
having to change anything on the compressed filesystem KNOPPIX/KNOPPIX.

SCSI-Emulation is active for all CD-Roms (unless you switch it off by
using the "atapicd" option), so IDE CD-Writers should work with the
installed versions of cdrecord and cdrdao (or the graphical frontends
thereof, k3b for example).

If your BIOS does not support el torito booting from CD, you can create
two bootable floppy disks by issuing (from Knoppix running on a different
machine) the command "mkbootfloppy", which will create a bootable
Kernel-disk plus a disk containing the initial ramdisk, which will be
prompted for at boottime.

If you wish to remaster the CD, please don't forget to specify
-no-emul-boot -boot-load-size 4 -boot-info-table \
-b boot/isolinux/isolinux.bin -c boot/isolinux/boot.cat
as option to mkisofs. Otherwise your CD won't be bootable. The
directory KNOPPIX, containig the compressed filesystem file "KNOPPIX",
must be located in the top level directory of the CD.

Caution: X-Screensaver: Don't start xlock or any screensaver that
requires a password. There are no default passwords on KNOPPIX,
i.e. all accounts are LOCKED unless you explicitly set a password.
See also README_Security.txt about this issue.
If you accidentially hit the screensaver button in KDE,
switch to one of the textconsoles by Control-Alt-F1 and kill
the screensaver (or just set a password for the knoppix user).

If you would like to edit your X-Server configuration manually
(/etc/X11/XF86Config-4 for XFree86 V4.x), use "knoppix 2" to boot
into runlevel 2 (textmode only) and, after changing the X
configuration, start the X environment with "init 5". Note that
you can always leave the graphical environment with "init 2", and
restart it later with "init 5".
