Without having read the whole thread, have you tried deleting the hibernate file (hiberfile.sys) at the root of your boot drive? It can get corrupted and screw the hibernation process. Turn hibernation on after deleting the file and it will get re-created (cleanly hopefully).

Still, I think something has changed in the laptop, because I could also bring it back out of hibernate by moving the mouse or hitting any key. Not so now, which is why everything is set to never and I won't allow it to go to sleep; this means it will consume more power. So much for these companies trying to go green.
