To set a VESA video mode, you have to set AX = &H4F02 and then put the
video mode (&H111, &H114...) in BX.  Then do the INT &H10.  As far as
actually doing anything in these modes, I know how to set pixels in the
256 colour modes (that's easy, just write bytes to the video buffer) but
as for the high colour modes I don't know how the pixels are stored.  So
if anyone does, let me know.
