Well, we could easily do it only if it was D0 _before_ resume.
But quite frankly, before I worry about "huge power surge" issues, I want
to feel like the architecture allows for clueless driver writers, and
still giving us reliable suspend/resume.
Once we have that reliability, and only _then_, do I care at all about
power issues. Make it work first, and not result in a dead machine if
there is unlucky shared interrupt timings.
