As I mentioned in IRC in this conversation, I had someone on IRC earlier 
who was experiencing this crash, with an ATI card in. I hope whoever it 
is chimes in this thread, because I can't remember the name. However, 
that leads me to think this isn't a nvidia issue - seems a little 
suspect that something would break in both nvidia and ati drivers to 
cause the same bug.
