     This isn't my problem - I have no troubles when I set up my card as a
Color VGA, and tell QEMM to Include the area from B0000-B7FFF.  For the ATI
card, at least, all the SVGA modes use the A0000-AFFFF bank for graphics.
I know that a VGA card can coexist with a monochrome adapter that uses the
address space B0000-B7FFF; my question is sort of like whether a VGA card
set up as mono VGA can coexist with a CGA card.  My card seems to be able
to handle it, for programs that aren't confused by the graphics + mono text
addressing arrangement.  Desqview does not seem to be such a program.
