LinuxQuestions.org - X Windows

This is my first time installing linux, I think I got through the installation okay (using Debian netloader and a nice guide I found on these forums)

next up is X Windows. I'm having trouble getting X Windows to use my video card. The info on the computer is as follows:
P2 333mhz
96 megs of SDram
OnBoard Riva TNT 128 (auto disabled through bios)
OnBoard Sound
OnBoard Ethernet
ATi Radeon 7000 (PCI)
USB 2.0 PCI Card

I want to use my PCI Radeon card because I'm going to need the S-Video output on it enventually. Anyways, here's what X-Windows is spitting out at me when it fails:

Code:

(II) Loading sub module "int10"

(II) LoadModule: "int10"

(II) Reloading /usr/X11R6/lib/modules/linux/libint10.a

(EE) ATI(0): Cannot read V_BIOS

(WW) ATI(0): Unable to initialise int10 interface

(WW) System lacks support for changing MTRRs

(EE) ATI(0): Adapter has not been initialised.

(II) UnloadModule: "ati"

(II) UnloadModule: "int10"

(II) UnloadModule: "atimisc"

(II) Unloading /usr/X11R6/lib/modules/drivers/atimisc_drv.o

(EE) Screen(s) found, but none have a usable configuration



Fatal server error:

no screens found

I've tried using XF86Config with both a generic VGA device and specifying the radeon drivers. I can't get either to work. It's generated the same error everytime.

I have no idea what to try from here -- any ideas?

Thanks,
