You would need to add (or copy/paste from UAE) all the Amiga custom chips, the 
Zorro bus, and implement the MMU (currently is anything but finished in 
Laurent's words)

You would need to add (or copy/paste from Aranym) all the Atari Falcon 
not-so-custom chips, and implement the MMU.

Most of the hardware (but a few required ones like SWIM) is already in QEMU, 
you need to glue everything, make Toolbox be VERY happy about its environment, 
make Mac OS boot so it can second-boot Linux (the direct-booter is so buggy it 
may introduce phantom bugs on the emulation) and implement the MMU.

Linux requires the MMU and an almost complete hardware emulation.
Standard m68k emulations (UAE, Aranym and specially BasiliskII) try to patch 
the OS to work.

Indeed BasiliskII is anything but a real macintosh emulator, as it patches 
heavily the Toolbox and Mac OS (that's why Linux and A/UX will never work on it)
