Hmm... hibernate "should" work reasonably well, regardless of the
underlying firmware. Are you booting via EFI or via the "legacy BIOS"
(which at some point was referred to as BootCamp)? You may want to try
the other one, just to see if it helps.
How did you initiate the hibernate?
What does `cat /sys/power/disk` say?
Try changing it, e.g. via `echo shutdown >/sys/power/disk`
(that won't help for suspend but it might help for hibernation since
step 3 above suggests that the machine didn't *really* turn itself off).

FWIW, I'd expect `nouveau` to behave a bit better w.r.t suspend/hibernate.
