Kan's patch does this for initial domain creation and could easily be extend
to cover adding devices (thinking about it, it may do already but I'd have to
check the Xend internets), and is fine as far as it goes.
It just doesn't seem clean to have the device safety logic in Xend *and* in
the hotplug script.

Dave: Skateboards have wheels.
