Tricky. I have been working on this before and the approach I took (and
seemed most likely to succeed) was to look at each syscall and see if it
was directly or indirectly MD or MI. I could do this before I have an
Alpha assuming that we don't need a working Alpha port yet. The question
is if we have enough time for it? On the other hand, it doesn't have to
be perfect, as long as the i386 port works...

I should have the tarball somewhere as well (at least the one Andrew
made "public"). Send me what you've got (to make sure I have the latest)
and I'll take a look at it...
