Gentoo: mount: special device /dev/hdg* does not exist [resolved w/ reinstall]

very frustrated right now, been up for a few days and on my fourth reinstall and now this.
on my last reinstall I changed from xfs to reiserfs because of the warnings in the manual. now, when I reboot i get the error message for all drives: mount: special device * does not exist
I have searched all over these forums and others, google, etc but no one seemed to have a definative answer. here is my fstab (and my partitions are fine if i boot up with a mandrake rescue command):
now, i recompiled my kernel three times, i have reiserfs support enabled and each of the options mentioned in the instructions (virtual drive support, etc)
I'm at a loss and this is the first time this error has come up. oh yeah, im using gentoo-sources for my kernel sources.
Well, this has been a long weekend... i hope someone has some insight for me because i dont think i can stand another install.

this is what the bootup screen says (only things that looked like errors):

VP-IDE: detected chipset, but driver not compiled in
VP-IDE: chipset revision 6
ds: no socket drivers loaded
FAT: bogus logical sector size 0
VFS: Mounted root (reiserfs filesystem) readonly
remounting root filesystem
checking root filesystem
reiserfsck: cannot open filesystem on "/dev/hdg7"
warning fsck.reiserfs for /dev/hdg7 exited with signal 6
filesystem repaired
remounting [ok]
checking all filesystems
fsck.ext2: no such file or directory while trying to open /dev/hdg5
mount: special device /dev/hdg8 does not exist
mount: special device /dev/hdg9 does not exist
mount: special device /dev/hdg10 does not exist
mount: special device /dev/hdg11 does not exist
<then the shit hits the fan>

here's my fstab:

# /etc/fstab: static file system information.
# $Header: /home/cvsroot/gentoo-src/rc-scripts/etc/fstab,v 1.10 2002/11/18 19:39:22 azarah Exp $
# noatime turns of atimes for increased performance (atimes normally aren't
# needed; notail increases performance of ReiserFS (at the expense of storage
# efficiency). It's safe to drop the noatime options if you want and to
# switch between notail and tail freely.
# <fs> <mountpoint> <type> <opts> <dump/pass>
# NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.
/dev/hdg5 /boot ext2 noauto,noatime 1 2
/dev/hdg7 / reiserfs noatime 0 1
/dev/hdg6 none swap sw 0 0
/dev/hdg8 /usr reiserfs noatime 0 0
/dev/hdg9 /var reiserfs noatime 0 0
/dev/hdg10 /home rieserfs noatime 0 0
/dev/hdg11 /opt reiserfs noatime 0 0
/dev/cdroms/cdrom0 /mnt/cdrom iso9660 noauto,ro 0 0
proc /proc proc defaults 0 0
# glibc 2.2 and above expects tmpfs to be mounted at /dev/shm for
# POSIX shared memory (shm_open, shm_unlink). Adding the following
# line to /etc/fstab should take care of this:
# (tmpfs is a dynamically expandable/shrinkable ramdisk, and will use almost no
# memory if not populated with files)
tmpfs /dev/shm tmpfs defaults 0 0

here's my grub.conf:

default 0
timeout 30
#root (hd0,4)
#kernel /bzImage root=/dev/hdg7
title=Windows XP Professional
map (hd1) (hd0)
map (hd0) (hd1)
root (hd1,0)
rootnoverify (hd1,0)
chainloader +1
root (hd0,4)
kernel /bzImage root=/dev/hdg7

it worked when i had my hd formatted the same way but with xfs (wish i never changed now, ridiculous...) so i doubt its a misconfigured grub.conf. also, if i change the params it won't boot at all.

also, i see people posting long messages like this that seem to be files. where are they located at? that is, are these boot up messages printed to a file and, if so, where can i grab them from so i can post the whole thing?

so, can i use the kernel from my mandrake cd safely?
(like put the vmlinuz image in my boot and change the path in grub to point to kernel=(hg1,4)/vmlinuz; or just rename vmlinuz to bzImage)
That way at least I could make sure it was my kernel that was the problem. Will this harm anything?

I got 3 cd/dvd drives, a zip, and my two hard drives are on my raid controller (master on each puts 1st at hde, 2nd at hdg) thanks for the effort though.

I saw a new error that i didnt see before,

/dev/hdg5: superblock can't be read

I'm going to try and fix it somehow (don't know yet) and then I'm going to reformat and start again....yeah, this is fun

In saying "other forums" you meant the Gentoo forums right?

If you have another PC handy, I'd also join into the Gentoo IRC channel - they can usually fix problems rather quickly in there (I've used it many times )
