The problem with the Compaq "Panther" P9 386sx had, as I recall, 
something to do with the motherboard design, rather than with the
fact that it used a 386sx chip.  In other words, this issue (and
the fix) were specific to that particular model of Compaq rather
than to 386sx chips in general.

To the best of my knowledge, there are no generic issues with
running any SCO '386 product on a 386sx chip.  Of course, there may
be problems with a particular manufacturer's motherboard, just as 
there are problems with motherboards using 386dx chips.

I hope this clears things up.
