	Nope, IIRC.  VESA 2.0 is just width, height, depth, palette, and
linear framebuffer address.

	Yeah, you will need a separate utility to specify the timings for
the VESA modes.  S3 cards work like this, too - s3vbe20 will give you VESA
2.0 modes at whatever referesh rates the author preset, but you still need
the S3REFRE.EXE utility to tweak the timings of the individual modes.
