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

Title:
  Crash on display change after resuming from suspend

Status in “nvidia-graphics-drivers-331” package in Ubuntu:
  Triaged

Bug description:
  Every time I put my laptop on suspend, then resume it, I get an xorg crash every time I try to change the display.
  It doesn't matteri if I try from a secondary display to the primary or vice versa, or from a dual display to a single display setup.

  When I ask for a display change, both displays go black, and the hard
  disk LED shows a lot of activity. This lasts around 20 or 30 seconds,
  then xorg crashes.

  I have to shut down and restart the computer before I can successfully
  switch displays again.
