Whoa...I thought you said that sort of thing didn't work with DPMI...
which is the only extender interface supported by V2, n'est-ce pas?
AFAIK (although I'm not really involved in this, so my opinions should
be taken with at least one grain of salt...) the only real way to
handle graphics in V2 involves messing with BIOS routines (some of which,
of course, can be replaced/supplanted with port i/o) and/or page frames
in DOS memory.  Microsoft can be _so_ irritating at times... :-)
