So Wander, I had a short look in to the opentom.org project and have got a lot of new questions: - does the opentom.org kernel support the original "suspend to RAM" functionality of TomToms kernel? - is there anybody using this functionality? - has somebody measured the power consuption in the sleep mode? - the opentom kernel has a file "/arch/arm/kernel/apm.c" which is not in the normal Linux kernels. Where comes this file and other power saving infrastructure from, where can I grab it, is there anyone else out there using it, on which device?
