I just built an Athlon 64 box with an Nvidia GEFORCE FX 5700 LE video 
card about 3 weeks ago. I have not had the problem you report. 
Everything worked AOK until I did a dist-upgrade using apt-get several 
days ago. It upgraded all the X related files and X then started 
crashing very frequently (just moving some windows could cause a crash) 
and it crashed every day even without doing anything. I switched from 
using the fc2 shipped nvidia GEFORCE FX driver to a generic VGA driver 
and the problem has disappeared. You might try the generic driver until 
you can find a better driver.
