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.
