I want to mention that last time the problem of making Linux-m68k emulation
work on NetBSD/m68k, it was concluded that this can't be done (easily).
The reason was that NetBSD/m68k, at least on Amiga, Atari and a few others,
uses 8 kBytes page sizes, while Linux/m68k uses 4 kB page sizes, so that
some Linux binary segment boundaries are misaligned wrt. NetBSD page
boundaries. (Note that all this is from memory, so some details might be
wrong.)

Now come on. I've bootstrapped the 68060 / DraCo port on an Amiga 3000
with 16 MB of memory --- at least compiling 1 MB binaries shouldn't take
more than 3 hours when starting from scratch, and a few minutes when only
changing single source files...

This is probably correct. SVR4/m68k might be more interesting, as there=20
could have been a few commercial programs for AMIX.
