I got your mind now: it looks like you prefer a seperate patch for the
embedding. Let me explain why I have the embedding within this patch:
the pm_ptr() or pm_sleep_ptr() just optimizes out the PM functions, but the
PM funtions are still compiled, so w/o the embedding, it's impossible
to clean up the code with the modern PM macros.
