Apple have also used the same trick on their G5 Macs, presumably

I actually think some x86's have done the same thing, however the
firmware hides all that from the OS and the OS just sees a normal PCI
environment. So if we can't hide the mess in firmware, the next best
place is in drivers?

Do we even need stable domain numbers? If we do, aliases sound fine.
A more complex method would be to sort them by MMIO window address
or perhaps by phandle.

PCI ordering has been a bane in the past on x86, so I think stable
domain numbers is certainly desirable. Particularly since the domain
number may be influenced by module load order :( Alises followed by
sorting by phandle sounds great to me.
