Right so it tries to load a MacRISC2 PE because we don't really emulate
a MacRISC4 with U3 etc... and that isn't going to do it any good,
really..
I'm not *actually* sure where MacOS gets itself into a spin, it seems
to be poking at something at 0xf280_0000 which is somewhat odd as this
would be the IO space and we have nothing there afaik, but I am not
enough of a MacOS expert to figure out quite how to track down which
kext it gets into etc...
In any case, the machine we give it is definitely nowhere near a real
G5 and that might be the main reason. More work needed.
I'll still cleanup & submit my current crop of fixes in case somebody
wants to have a look.
Cheers,
Ben.
