Can you test the enclosed patch. It seems to be both simple and to 
resolve the resource collisions and the "No IRQ known" problem.
I added a smal comment (and modified another) so future janitors won't 
move pci_enable above pci_assign_resource again.
If everyone is ok, I can send it to Linus for inclusion in BK (I have 
the green light of Dave Jones).

Thanks,
