But isn't it true that the "special hardware" can simply be a 386 chip?
Now if the original poster had a 286 then special hardware (Chips&Technologies
NEAT chipset) would indeed be necessary.  With a 386 he would only need a 
memory manager (QEMM 5.1, 386totheMax, DRDOS 5.0, etc.) to capitalize on
the inherent memory mapping abilities of the 386.
