Many (most/all?) SVGA modes actually make use of addresses in the range
you have given away to QEMM.  The documentation for my paradise card 
explicitly states that A0000-C7FFF is used by the card in one mode or another.

Solution.. simply EXCLUDE=A0000-C7FFF to guarantee that things will work ok
(or EXCLUDE=A0000-BFFFF ROM=C0000-C7FFF for shadowing of VGA/EGA BIOS).
To gain back some of that precious "high memory area", make use of the
lower portion of the bios roms:   INCLUDE=F0000-F8000 FRAME=C8000
