KMS, right... another thing to try. So I did, I built an identical kernel, 
except that KMS was off. BTW, is there an option to toggle this by a boto 
parameter, like 'nomodeset' to diable the gallium stuff?

I get the same result, X crashes with similar errors.

Thanks, but my board does not even have AGP, and my kernel is recent enough.

I will have to file a bug at freedesktop.org. I tried to get more debug 
output by compiling xorg-server and xf86-video-ati with debug information, 
but when I start X with gdb --command=myXcmd as described in [1], I only get 
a blank screen with a cursor blinking at the top left, and when I try to 
switch back to a text console (I have to use Alt-SysRq-R/K before), my 
display goes into suspend mode. I am back at the text terminal, but I am 
blind, and have to reboot.
Ok, the bug is filed [2].
