I've determined how to prevent and induce this bug. If I run X with fglrx
(catalyst 10.8) and then remove it from my system (the module, the DDX,
everything), then modprobe radeon with modeset=1, and install mesa and
xf86-video-ati and libdrm from git, then X runs successfully with acceleration.
This persists across multiple reboots.

If I then shutdown the system and start it back up, the GPU locks up
immediately.

I suspect that fglrx is leaving a register in some magical state that persists
across reboots.
