I don't believe the NVIDIA closed source driver is suspend compatible.
I too had the same trouble and I switched to the open source nv driver
and on 2 out of 3 of my NVIDIA based systems it worked perfectly and
suspend/resume now works, mostly.

Hi,
I have a Toshiba Tecra A4 with an Nvidia video card and the nvidia
driver installed. I'm able to shut the lid and suspend the laptop
which works great. However, when I open the lid to resume everything
it "seems" to startup ok except I don't get any video.
Is there any options I can configure with the new power management
software to rmmod nvidia and modprobe nvidia?
(I believe this is what the problem is)
Cheers
