The "ati" driver doesn't seem to know how to talk to this chip (PCI-E ATi FireGL
V5000, PCI ID 1002:5653) correctly, so the screen is refreshing weirdly and
blinking (like a CRT with bad sync sometimes does, but less overlapping garbage).
Manually setting xorg.conf to use the "fglrx" driver (no other changes) makes X
work OK, though there's no direct rendering.
