There's many sub $100 MIPS boards available that have enough
resourses, barely, for a minimal system to boot/run on.

Yes.  Running off a real flash is much more difficult...

Those would be a good level to start from.  Subsetting is a pain
during development, but once developed, it shouldn't be too hard to
shrink things down.  Doing it generally might be an issue...
