IIRC the last time you posted the patch my comment was that I would be happy to take the patch as-is, as long as the extra PCI bus is added to the QEMU mac99 machine beforehand. Device trees shouldn't be advertising devices that don't exist within the machine, since the existence of a device node will indicate that guest OSs should try to probe for it and the behaviour when the device doesn't exist is undefined.
And also while I remember: this is assuming that the bus numbers are correct according to a reference device tree (I can't remember the exact outcome of the discussion as to whether each bus number is unique beneath the host bridge or throughout the entire device tree).
