I've applied these on top of my MacOS virtual memory branch at https://github.com/mcayland/qemu/commits/q800.upstream2-vm and I can confirm that MacOS 8.1 now boots here with virtual memory enabled :)
Possibly it might be worth including a tidied-up version of the "WIP: target/m68k: always exit_tb when changing sr with andi/ori/eori" commit from that branch which is also related to switching between supervisor and user modes under MacOS. Shall I tidy it up and send it to the list?
ATB, Mark.
