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?

Let me lookup the kernel bug and get the > exact kernel versions... 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].
