Yes, it's entirely possible, and seems like a good thing to do.

The original motivation behind it was to replace struct pm_dev and the
callbacks for it. I haven't looked it into replacing them in the APM code
or the power management code for other architectures, but it shouldn't be
that painful. Hopefully.
