Sweet. Looks OK to commit but before doing so I think we should work out
what is missing. I think we want to install a rules file with the
RUN="socket:/org/freedesktop/hal/udev_event" right?

Btw, I think we need to be able to support older udev versions for a
while (say, 3-4 months; we already require udev 057) so there should
probably be a configuration switch so we do the right thing, e.g.
install a rules file if using this new stuff and the hal.hotplug program
otherwise.

Thanks,
David
