No, it doesn't (can't) save/restore GPU state.  In fact, nvidia.ko may 
help when you are suspending from X11.  At least in theory, it should 
be able to save/restore GPU state correctly.  However, a NVIDIA 
engineer once told me that the code path wasn't tested well because 
he couldn't find a right laptop to test at the time.  It was long 
ago, though.
