Now that I have a clue of how this works I have to agree to keep it 
simple.  In the simple case of the MVME5500, once you've counted all 
the busses on the first PCI peer you know the higher busses are on the 
second peer, and you can hide all the PCIx stuff at that level.  For 
now I just have time to put in a warning if a PCI-PCI bridge shows up 
in a PMC slot, since that won't work.

I won't begin to ask how hot-pluggable PCI works.
