Dunno, but if you're trying to run DOS applications, a better choice
than qemu may be dosbox (http://dosbox.sourceforge.net).  Dosbox may not
be as fast as qemu, however, so that may not work for you.  But dosbox
does implement a very good DOS pc environment that needs to other
operating system or video drivers.  It provides standard vga (256-color)
and sound blaster support for DOS apps.
