The only architecture-dependent change is the 1542 one, but there are
probably architecture-independent changes.  (Especially since there
have been a number of updates to NetBSD recently, and OpenBSD might
not be able to track all of them.)

A while ago I exchanged mail with someone who was using a 1542 on some
old Sun machine with an ISA bus (I think a sun3--not a 386 machine).
On the other hand, a 386-specific solution would probably solve the
problem for 90% of the users (at least until people start using the
ISA bus on alphas).

This was my attitude 2 years ago.  Since then most of the people I've
seen set up development environments on PC's have refused to consider
NetBSD because of its lack of support for the 1542.  Now the PC's
around me are all running Linux, which means all my compiles run on a
single, 16 Meg NetBSD machine which of course swaps quite heavily
under the kinds of programs I like to run.

At this point, I have two hopes:  A quick, small, and dirty patch (one
I can apply each time I sup), or a new operating system that fulfills
my needs.  OpenBSD seems to be both :-).

I just took the one out of the dev directory.  Is there one under
arch/i386 somewhere?
