This is rather interesting, I am using the M1-ATX myself and have been pretty happy with it. The few things I dont like are the limited range of automated power off options (45 seconds or never?!?!?). In theory the power off is nothing more than a command that is interpreted by the apmd to call shutdown. I assume that if you found where the 'hook" is you could implement your own script that would call hibernate instead of shutdown. This could be very handy. If I wasn't stuck in Windoz right now I would look into it.. If you dont have any luck with it I will check it out when I get back home and am not tied to this hotel's internet connection .
