I looked through ts7800ctl.c, and there doesn't seem to be much there. I was
curious how the kernel was being notified about going into a sleep state, but
it seems the in-kernel suspend / resume /hibernate is not being used at all.
Surely there must be more than just using the AVR as a glorified power switch?
