Looks like the "firmware" of the card got stuck.
If that happens again, could you please try
echo "base=0xd0000000 size=0x10000000 type=write-combining" > /proc/mtrr
from the console, before restarting the X server with init 5?
(base=0xd0000000 size=0x10000000 are correct for my intel card).
This may reallocate at least the MTRR registers that got lost.
But, I wonder what the Xorg server is SUPPOSED to do when the GPU hangs?
