I can't help feeling that it's a bit simplistic to just say "re-init 
peripherals" like that.   Some peripherals can have quite a complex state 
associated with them, and just re-initialising them as though you were 
starting from power-up may not make the O/S happy when it finds itself back 
in control after the hibernation is over?

There has to be some O/S involvement in going into, and returning from, 
hibernation mode - the question for LinuxBIOS is "how much of a task is left 
over once you take out what the Linux kernel can already do for itself?"

Antony.
