I guessed the 810AGP driver in the kernel has gone haywire. I dropped 
back to kernel-2.6.8-1.541 since kernel-2.6.8-1.603 really bombed even 
at higher resolutions. The X is the same and works w/ the 
kernel-2.6.8-1.541 kernel for me anyway.

Other video cards are supposed to take advantage of this AGP and might 
also have problems because of some customization to the kernel driver.

There was a discussion on the development list regarding radeon and the 
AGP in the kernel. More accurate information might be available from 
reading this list archive.
