I've given this a quick spin on my MacOS images on a G4, and a basic boot to
userspace under qemu-system-ppc for MacOS 9 and MacOS X don't show anything
obvious
so far.

(It's a bit tricky to test much as something odd is going on with performance
here -
the emulator seems disproportionately slow during IO given the speed of the G4
CPU).
ATB,
Mark.
