No, you are right, unfortunately. qemus non-x86/x64 emulation targets (eg. sparc, ppc, mips, arm) are pretty incomplete. They are mostly designed to somehow get a linux kernel running. There is a more complete ppc emulator, PearPC http://en.wikipedia.org/wiki/PearPC , but when I last tried it it hasnt been complete enough either, in terms of whether it could ever be useful to serve as sort of reference platform for Polaris, being cheap (zero cost) and available virtually everywhere (in contrast to the PegasosII, ODW et al). Even if somebody ported qemu-system-ppc to be based on http://openbios.info/Welcome_to_OpenBIOS (designed after IEEE1275-1994), then it would still be a bad idea, as you never knew which bug/hurdle/stopper would be caused by Polaris versus qemu versus openbios. Take the qemu-system-sparc emulation target, for example: It is even based on openbios for over a year now, bus still unable to boot any Solaris 2.x or SunOS4.x kernel. It is out of the question for the desired purpose, except somebody invests many millions into it (if not billions). The Polaris port has to happen in a stable, reliable, typical configuration, that is totally predictable: Real hardware, or an emulator that would be complete (which doesnt exist for ppc). There is some emulation software on ibm.com, but it doesnt suit our purpose at all.
