Not entirely at hand, but I can have access if necessary. However what
seems mostly targeted as boot target is G3 (-machine g3beige) in qemu,
so there may be some differences (isn't G5 64bit?).

I tried booting Max OS X 10.2 using (boot cd:,\\:tbxi) but iirc it didnt like CHRP,

I also found Mac OS X 10.4 Upgrade DVD, so we can test another version,
it's boot messages on real hardware look a bit different from older versions (emulated),
but I think it's caused by newer XNU.

Trying OS X 10.4 on current trunk (modified to use cd:,\\:tbxi syntax) it stops similarly
to others versions printing:
call-method slw_update_keymap: exception -21

However in qemu with GSOC patched openbios it stops
after printing "Mac OS X Loader"
