Last year I installed an Intel Inboard 386/AT in my IBM PC/AT.  While
this is not exactly equivalent to replacing the motherboard, it's
functionally the same (the Inboard plugs into a 16bit slot and is also
connected via an umbilical cable to the 286 socket).  I was running
XENIX 286 2.1.3 at the time.   Worked like a charm.  I believe I manually
installed XENIX 386 beta over the previous installation some weeks later
without resorting to backups.

While I could imagine exceptions, in general, a 386 AT clone should be
able to run XENIX 286 without problems.
