sysfs is relevant for bigger systems but for small embedded stuff the whole PM layer is fairly "so what". At that level your hardware is tightly defined and you *know* the power management ordering. Policy becomes critical for performance and gets done at a very fine grained level - things like waking up the flash for a read then turning it back off on a timer for example.
