Everything involving suspension is managed by solid. Locking screen is handled 
by DBus, through freedesktop.Screensaver interface. The only additional 
dependency is X, that can be easily removed.

I have no experience in compiling in non-linux environments, so I really can't 
help here...

True indeed

Providing Solid and KDELibs run fine on them, I'd say there is no reason why 
powerdevil should not work there.

Of course, I'm always ready to put things back into discussion, especially for 
these kind of matters :) though in the current design I've already taken care 
of removing anything non Solid/KDELibs based from core components.

Agreed. I'd like to wait for Kevin too before moving, so I'll just push the 
move one week later I think :)

Cheers and keep me informed on the other platforms
