The latest PC Magazine reviews 14 80386SX-based computers.  "Two [of them],
the Everex Step 386is and the Twinhead Superset 490 use daughtercards on
their 16-MHz 286 motherboards..."  They also state that Everex offers the
daughtercard to owners of Everex Step 286 computers (12 & 16-MHz) for
$699.00.  They also state that "Cumulus Corp. and AOX both offer generic
386SX daughtercards to upgrade 286 machines."  Language used in the 
description of these products implies that Cumulus "anticipates" rather
than actually has available for shipment, their 386SX daughtercard.

Of course the article had to have been written as many as 4 or 5 months
ago thanks to magazine lead times and may not reflect the current situation.
I understand that AOX has withdrawn its daughtercard product due to some
sort of technical difficulty, however I'm not the authoritative source for
such information.
