Yes, I understand.  I'm quite happy with just taking whatever
Open Firmware tells us (and hope you don't need to put all
that many workarounds in _that_ code, heh).  The more I think
about it the happier I am about it.  I guess I got a bit scared
by the motivation, that's all.

Are you planning to in the future take _all_ configuration
space settings from OF properties?  That would be a logical
next step, have the kernel not try to redo any of the PCI
configuration...
