I'm not suggesting we hold off on everything until they're in, just
saying it'll simplify things once they are.

I'd like to get to a point where we can ship out of the upstream
kernel and that's going to need power management to work.  If we can
sort out wakelocks (as it seemed like we were getting close to),
that's one less difference to maintain.
