Actually this may be a red herring, since the AAPL,address properties are present in the G4 AGP device trees but not the G4 PCI device trees. So unless G4 AGP are old world then this patch might be a red herring. Alex?
I think all G4 Macs are New World as it started somewhere around G3 and all later models had New World ROM (that is OpenFirmware without Toolbox). So I'm not sure why you don't see these in G4 PCI or if you do it's not because of Old World ROM.
The model id we have now (PowerMac3,1) is corresponding to the G4 AGP and I've picked this because it is the minimum required by MorphOS. Previously it was probably some PCI model but the set of devices currently emulated by QEMU may not really correspond to any of these real machines.
There are some reports over on emaculation that OS X 10.0 and 10.1 hang in QEMU when trying to initialise the display, while 10.1 can run fine on PearPC. I wonder if it's something to do with the fact that PearPC provides a PCI rather than an AGP graphics card?
