I also have the same symptom when upgraded to this driver.

My machine is:

Intel I7 920
Asus X58 Motherboard
GTX460 nvidia graphic card


After a resume, i noticed that everything looks fine.  (since i have dual 
monitor), i could work on the first monitor (monitor to the left), but as soon 
as i move my mouse cursor the second monitor, Xorg service locked up.   

I then ssh*ed* into the PC and attached a debugger to the Xorg process,
the stack trace showed that it was running code inside the nvidia driver
and never returned.  CPU consumption at this point was 100%


Please let me know if you need me to run any test scenarios; this buy is very 
easy to replicate on my PC.  Just put it to sleep on RAM, and on the next 
resume, Xorg would lockup when the mouse cursor is moved on the second monitor.


thank you
