Wow, that's a fantastic bug. Should be fixed in 2.6.31-0.183.rc7.git5 or later.
It has re-appeared, and also is worse. Now there is no graphics and no VGA (and no VT2) at all for multiuser login. Also, at boot the VGA console has a couple dozen lines in yellow that look ominous. I will attach the relevant portion of /var/log/messages. Perhaps the best summary is: ----- [drm:radeon_ring_test] *ERROR* radeon: ring test failed (sracth(0x15E4)=0x00000000) <<ship>> fb: conflicting fb hw usage radeondrmfb vs VESA VGA - removing generic driver -----

can you retest with a newer kernel?
