Any idea where this should go?  Might be time to grow a tool that grok's 
the newbus hierarchy and pushes requests to devices.  I've wanted 
functionality like netbsd has recently added to control power to devices 
and this would be seem to be similar.  Not sure if we can do something 
that'd unify programs like atacontrol and camcontrol (or whether this is 
a good idea).
