If I recall correctly from some 25 years ago, memory address mapping
(which is what a MMU does) is mandatory for preemtive multitasking. An
i286 can't run a Unix-like OS either.


In 2008 I tried to get FreeBSD down to its minimum, too. The success
post is about all what's left today:

The task to get there is simple and straightforward, but time consuming:
go step by step through the kernel configuration to disable whatever you
can spare. Configure, build, try, repeat. If you need a small entire
system, do the same for packages and every single file you copy into
your system image.
