Hmm, some questions:
- check top(1) - is X eating up all the CPU cycles?
- which driver is Xorg actually using?
If it's actually nv, I have seen issues like that with NV40 hardware -
some rectangle fills never complete, the driver waits, times out,
resets the blitter, moves on. The visible symptom is X eating up
ridiculous amounts of CPU time.
