That is possible.  But getting XF86 executables work first for
NT would a good start.  At some point either we or any other
contributr
may come up with solution for Win9x.

Beside XGGI drivers from John Fortin would definitely run on Win9x.
XGGI supposed to be platform independent, though it is not really
an XFree86 itselg.  It does use XF86 drivers and libs.
