How about triggering the BIOS mode change just after calling InitGraph?
It's an INT 10H function (but I forget which one).  Then the BIOS tables
will be set correctly as well.  Just be sure to reset them after you're
done by using another BIOS call, since TextMode probably doesn't reset
the tables either.
