Sounds suspiciously like you're not passing a video argument to the kernel.
I'm not familiar with your video card, but if it's ATI mach 64 based you can
use something like video=atyfb:vmode:20, cmode:24, and if it's 128 based just
change the atyfb to atyfb128, and boot linux, rerun Xconfigurator. If
Xconfigurator recognises all your vram, then you should be on you're way.

Got trouble with your X?
