F-16 suspends my *desktop* after 30 minutes at the gdm , making it impossible to ssh in

If it supports LAN-triggered wakeups, I don't see why it should be fully on :-)

Not sure if Fedora 16 has the infra, but in my OLPC-tinted-glasses
view, power mgmt / NM should allow you to say "wake-on-LAN on this
interface", then set the WOL bits when it's going down.

(Note! The WOL bits need to be frobbed every time the system goes to
sleep. They get cleared on wakeup.)

Thanks for helping keep the Earth warm! :-/

OK, that's a whole another topic.

That's such a 90's thinking :-)

At this stage, and looking forward, suspending on idle is a good idea
on /servers/, where you save power at the server and at the AC.

There is work to do across the stack to make S/R work smoothly and
transparently. OLPC is doing much of it -- help us getting it into
mainstream code (and thinking!).

Or join the greenpeace in teaching polar bears about the wonders of
tropical climates...
