There's nothing there for the problem I'm talking about here (devices
that haven't been enumerated yet) and I don't off the top of my head
know if the enumerated case is supported by any buses in Linux yet.  It
is part of the DT specifications and has been implemented on other OSs
but I'd need to go check if Linux actually went and implemented any of
that.
