I just found out that suspend-to-RAM works fine.

After a successful suspend-to-RAM also suspend-to-Disk (hibernate) works OK
*UNTIL* you restart the X server. I guess suspend-to-RAM disables vblank
interrupts and they don't get restored until the X server is restarted...

Suspend-to-Disk actually doesn't freeze the machine, I just didn't wait long
enough. Suspend-to-Disk returns after about 2 minutes, but the machine has
become unusable (/ is gone). I guess the pm tools can't recover from a freeze
failure at this state anymore.
