That's very interesting, and well done for figuring it out and saving
the system. Strangely, my problem just went away: my laptop's been
hibernating fine since about a week after I started the thread. I put
it down to a kernel update. That being said, I don't hibernate
regularly, so maybe I've just been lucky :p
