Responsible-Changed-Why: 
I'll take this enhancement.  I indepedantly did the same kind of thing
and have requested a repo-copy of sys/isa/*ppc* to sys/dev/ppc.  I will
look more at this implementation after that is done.  At first pass
though it doesn't seem to address the bus bug issue in puc when you
have a chaining of puc -> ppc -> ppbus -> plip for example.  There might
be code in this patch to work around it in another way.
