Holidays etc.. I _think_ the patch is good, but would really like
someone else to verify, its too simple to be right :-)

Thomas said he'd bend his brain around it, but he's been having holidays
as well and isn't back from them afaik.

As for completely reworking the whole hotplug crap, I'd fully support
that, there's a lot of duplication in the arch code that should be
generic code. Also lots of different ways to solve the same problem
etc.. lots of different bug too I bet.
