Intel is now shipping '386s that have the Erratum 21 bug fixed.  You can
identify the fixed part by the DX suffix in its part number: i80386DX.

Bell Technology, Ironwood Electronics Inc., (612) 431-7025, and others
I suspect, offer hardware fixes for this Intel problem.  I have not used
any of these products, so I cannot personally endorse any of them.
 
It would seem reasonable to approach Intel about replacing a buggy chip
with one of their new DX parts.  How could they refuse?
