Same as everybody else - /sys/power/state.  It is very important for us
to keep as close to the standard interfaces as we possibly can.  There has
been far too much fragmentation in the past, and we don't want to be 
guilty of that crime.  We will have some new interfaces that are unique
to OLPC, but we'll try to work with the linux-pm folks to ensure that
we do the right thing.

I'm not sure what you're talking about.  All control will happen through
/sys, again - like our PM counterparts.

Right now, I think that USB needs the most help.
