There is (or was) also PC/IX, a system III implementation.  I believe it was
implemented by Interactive and sold by IBM.  I used it for a couple of years,
and YES it is very slow when compared to a 286 and especially a 386, but at
the time most of the work I did was on a PDP 11/70 running PWB Unix with around
40 users and the XT with PC/IX was at least an order of magnitude better.

However, in answer to the original post, PC/IX was limited to 64k text and 
64k data, so i think this would preclude X.
