MAME/MESS can boot MacOS. There is work under way to boot MacOS in qemu-system-m68k. But outside of A/UX, I don't know of any way to get hardware assisted virtualization for 68k MacOS applications.
It didn't work on Linux last I checked, but Basilisk II has support for running directly on the CPU in NetBSD while only emulating the supervisor instructions (it used a signal handler to detect and handle anything that would cause an exception). I looked at the code, and it appeared to be possible to do the same on Linux with some tweaks to the signal handler (Linux passes the extra context differently). However, Basilisk II can only boot MacOS because it doesn't actually emulate all the hardware. In a few cases, it emulates synthetic devices and inserts its own drivers with fake expansion ROMs. This means you can't run Linux, NetBSD, or A/UX. Brad Boyer flar@xxxxxxxxxxxxx
