I've had trouble parsing these suggestions. I can certainly 
hack up some pci-host structure so I can publish a few stats
(the goal is to eliminate /proc/ppc64/eeh).  By "hack" I mean
something that would live with either the rpaphp code or the 
powerpc code. However, this is a different type of activity 
than the idea "define a generic architecture-neutral pci-host 
bridge structure".

Maybe I should just do the first, and if it ignites anyone's
imagination, we can talk about the second.
