I have the same problem. ubuntu 64, nvidia gtx260, flash non free, and so on.
Display became garbled, mouse slowed down, things broke in general, only hard reset would help.
I would very much so like to test it with firefox 3.5b99 and such, but there is no 64-Version provided.
FF version 3.0.11 did not bring any improvement. I switched to Opera now, and my system works just fine.
