The current interface was written a few years ago for
2.4, when I couldn't find a general PM interface to
start with.

That would help, though I'm not sure when I would get
to it personally. I'm working on 2.6 updates at the
moment with some other developers, but PM is not on
our list for now. If you're dying to work on it and
hardware is the only issue, I might be able to help :)

Not that I know of, and not the way the Au1x supports
it.
