No, I didn't find any way to trigger the problem on purpose.
295.71 driver (current version) doesn't work right away after start but 
doesn't freeze OS.
Older 285.05.09 version appears to work fine for a long while (1-2 
days), then freezes OS.
I am pretty sure anybody will see the problem if they try this version 
of driver with 9400 GT card.

I did send the bug report to NVidia's address 
freebsd-gfx-bugs at nvidia.com. So far no response.
I am not sure how such one way, secretive, PR handling works in general 
for any product. So not sure how NVidia can manage it. No way to track 
the issue with NVidia.
