Changes from v1:
- Restored the 'sc 1' support to avoid breaking the pegasos2 machine.
I tested this version in the G4 with the following OSes:
- Linux 5.15 (5.16 seems to be broken, even with master)
- FreeBSD 13
- Mac OS 9.2
- Mac OS Darwin 6.0
- Mac OS X 10.4
- MorphOS 3.15 (-M pegasos2 and -M mac99,via=pmu)

Just out of curiosity have you tried booting MacOS 9.2 under KVM-PR? Last time I
tried on my G4 Mac Mini here, OS X worked fine but 9.2 failed early after jumping
into the 68k emulator. Unfortunately due to the split real mode (see
https://github.com/torvalds/linux/commit/c01e3f66cd5cdc1f727f4c7b0c10b3e3bdb91ba7
where MSR_IR != MSR_DR) I can't step through with QEMU's gdbstub to see what is going
wrong...
ATB,
Mark.
