You might want to rephrase some things on your web page then. The page says: "The mac-on-linux project does not utilize an emulation library. Instead it emulates the hardware of the machine. " and "As stated above, all hardware must be emulated. " and "The processor emulation is fairly complete, with some exceptions:" Now maybe it's just me, but "processor emulation" sounds just like PSIM. It sounds like your approach is better, but your web page is confusing on this point. Emulating the whole processor and emulating priveliged instructions only are two very different things.
