KDM crashes after resume from suspend (S3)

[Murz]

I have using Kubuntu Jaunty AMD64 on ASUS M3N78-EM (NVIDIA GeForce 8300 chipset) with internal video and NVIDIA Driver Version 180.44. KDM version is 4:4.2.2-0ubuntu2.
At default, it each time didn't resume nomally after S3 suspend, because it didn't start HDD after resume. I have added "pci=nomsi" parameter to kernel, after this it goes to suspend with hands and wakes up normally: after resume I see my locked KDE session with all loaded programs.
My computer go to S3 suspend after 15 minuts of inactivity.

But 7 of 10 times after automatic suspend and resume I see clear KDM login screen instead of suspended active KDE session!
At this time in /var/log/kdm.log I see:

Backtrace:

This is actually the Xorg server crashing, not kdm, so I'm reassigning the bug to the nvidia driver.

I'm sure that the Xorg bug team would like to see the following:
-A copy of the output of the command lspci -vvnn (two v's, not a w)
-Copies of /var/log/Xorg.0.log and Xorg.0.log.0ld

I have detect the source of the problem!
Xorg crashes only when machine go to S3 sleep with active Virtualbox on fullscreen! And when virtualbox is in window, it sleeps and resume normally.
I have created a bug report at virtualbox bugtracker: http://www.virtualbox.org/ticket/4169

a very similar problem exists on mine. I am using NVIDIA 190.53 drivers, and the same thing happens, but VirtualBox has nothing to do with it for me.
