How's the AVR32 off for power support along the lines of suspend/hibernate? What kind of effort would it take to implement, anyone know? The AVR32 is of course a low power chippy, but a bit of suspend/hibernate action would be really very nice indeed :)
What kind of issues am I likely to face if I simply implement a custom syscall or ioctrl in a driver to simply enter a sleep mode? Making sure of course that anything talking to the outside world has finished doing it's thing.
