Does OS X have a blessed open firmware boot script? Could it be modified to boot other OSes through yaboot?
You can consult the FreeBSD.org's forum member "sossego" (http://forums.freebsd.org/member.php?u=4804) on this issue. He/she's expert on PPC & Open Firmware, I have consulted him/her several times, too.
