Ok.. I think it's pretty easy doable if the bus number registers of the bridges are filled reliably. Is this the case?
Yes. And the bus number values are also in the device tree. Which is where it would be better to read them from. Just in case we have a non-standard pci bus. Like the Opteron's multiple host bridges off of one cpu.

this is in the openfirmware kind of view a device node vs node property consideration. Does a single slot need more information than the fact that it's there?
Yes. Which the irq routing information.
This information is also held in the pirq table. Can it be generated from there or are there other caveats? It would be nice if a new board only needs an adapted pirq table, no matter whether it provides an mptable or not.
