Agree

Agree as well

OK

There's no problem. It's only weird that we do hibernate/suspend in HAL 
and sending "wake"/"sleep" signals in gpm. Since both of these are 
heavily related I'd expect they would be in the same module.

I.e. sending the signals and implemeting the hibernate/suspend method 
both in gpm or both in HAL

Is it a problem to both in HAL?
