Well if your hardware runs off-while-idle or even just retention-while-idle, then the basic shell works just fine waking up every few seconds or so. Then you could keep init/shell/suspend policy deamon running until it's time to suspend the whole device. To cut down runaway timers, you could already freeze the desktop/GUI/whatever earlier.
