The pci_pci code actually needs some other changes done. Note the comment
at line 267, "If this is a 'default' allocation against this rid, we can't
work out where it's coming from (we should actually never see these) so we
just have to punt." The "we should actually never see these" part is not
quite correct, since NEWCARD uses default allocation to automagically get
an "unused" range from the pci bus. Then we have to tweak the window for
the pcipci bridge to forward the new addresses if the window wasn't big
enough. Not to mention, we still need to implement a way to request bus
numbers properly...
Bleah, hardware sucks. Give me a virtual machine.
