I found this bugreport: https://launchpad.net/distros/ubuntu/+source/acpi-support/+bug/30768
and this solution is even easier: https://wiki.ubuntu.com/NvidiaLaptopBinaryDriverSuspend
For me works sleep -> wake -> hibernate -> wake (more times I don't try).
I think nvidia-glx-config script should modify /etc/default/acpi-support to enable suspend and hibernation.
