Yeah, this is a central point of the discussion: pmf can (currently) only do
tree walks and power down things bottom up.
Now what you (and others) describe makes sense for obio/mainbus like "buses",
but do we expect, say, a pci card to survive the pci bus bridge being powered
down? For what value of "powered down"? And can we make pmf deal with this?
