AFAIK, Windows does it by simply ignoring the BIOS and
programming the chipset directly to change the video mode.
This would be possible in the XFree86 driver, too (in fact,
the i810 driver does it this way) *if* Intel where to
release the programmer's reference manual for the i810M
graphic controller, which they haven't so far :-/

The alternative is to disassemble the relevant portions of
the Video BIOS to reverse engineer the needed chipset
programming.  That's, however, going to be much more time
consuming.

So, if anybody has good contacts to Intel, that could help
us.

Cheers,
Manuel
