Microports (a spinoff from Digital Research) has a System V for the 286; I
think Microports was started when Digital Research dropped their work on the
official AT&T err, umm, microport of System V to the 286.

Don't hold your breath.  4BSD gets very upset when reminded that sizeof(int)
does not necessarily equal sizeof(long) (although I remember seeing
something in S5R2V2 for the VAX which looked like it had caught the same
disease), and the 286 doesn't really like 32-bit arithmetic (even less so
than the 68010, which at least has 32-bit registers and 32-bit
move/add/subtract/bitwise boolean/unary arithmetic operations, although it
doesn't have 32-bit multiply/divide and it does some of the rest 16 bits at
a time) and thus has 16-bit "int"s.
