That's your answer. To be able to use these modes under FreeBSD the
VESA BIOS Extensions need to be on-chip. It appears that yours, like
my ATI card, aren't (Matrox, and newer ATI, cards are). To support
these modes in DOS (for Lotus 1-2-3 for example) it needs a DOS TSR to
provide the necessary support.
