For me the problem was the nvidia card (or more specifically the nvidia driver). 
Suspend works for me using current nvidia driver (currently 190+, don't remember 
what happened with older ones) and current kernel (2.6.30+).

I do have some issues with an external screen after restore, but everything else 
works fine.

As for hibernate, I'm using tux on ice and appart for a 1 minute delay at 
startup again due to the nvidia hardware everything is good.

This is with recent debian BTW. Also for hibernate I had to change the turn of 
method in pm utils, I believe it was from 4 (acpi hibernate) to 5 (shutdown)
