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.
