I think the way you'll have to fix this in the meantime is to use
pci_create_root_bus() directly so you can do things in this sequence:

  pci_create_root_bus
  pci_scan_child_bus
  pci_bus_assign_resources
  pci_bus_add_devices

dino_probe() is an example of similar code that does this.

Erm, but isn't this problem going to strike any system that doesn't
have resources assigned by the firmware?

If so, a common 'pci_scan_bus_from_scratch' would at least highlight
the problem and centralize the work around until it is fixed...

Many embedded systems will require this..

Yep, agreed on all counts.
