The proprietary drivers are not provided by Fedora, and really, they
are unsupported.

I'm not sure. You could try running:

killall gnome-power-manager
gnome-power-manager --verbose

and see if gnome-power-manager causes events when the monitor wakes
up. It could also be an X bug, or even a nvidia bug.

Sounds like your system doesn't support suspend. Arguably, it's also a
bug where the suspend menu item is displayed in this case.

According to HAL your system doesn't support suspending. What's the
output of "cat /sys/power/state" ?
