I looked into this on behalf of my employer some time last year. The MMU
will need a new pmap, as it's basically just a software-managed TLB
(though maybe the TLB miss handler could be made to walk regular 68k
page tables). The other differences are easy enough to support.
Given the right hardware, a port won't be difficult.
