What PM toplevel core changes are you referring to? I've look over the
changes to pm_ops and they seem to make sense. Still I almost wonder if
we should make the entire thing arch specific code, and then have this
code call things like device_suspend(). If mac hardware required that
many new hooks, then other platforms might require even more.
