I think VESA is from the 80386/80486 era, and that even
Pentium 1 (desktop) computers started adopting the PCI bus for
several reasons, including the replacement of the
short-sighted VESA bus. So, a Pentium 3 should heavily
post-date VESA.

Yes and no.<br>

You're thinking of the VESA LocalBus slot, which was short-sighted
only in the sense that it was designed by a bunch of video card
mfgrs to make their products look good - it did exactly what it was
supposed to, and it was cheap enough that m/b mfgrs (mostly) just
implemented it without putting up a fight.<br>
<br>
However, VESA, the association, continues to define standards for
video-related things today. Some of the most important bits are the
spacing of the mounting holes on the back of LCDs (yes, seriously),
and a common definition of how to set video cards into a certain
resolution with a linear, non-accelerated, frame buffer mapped to a
certain address space... this latter piece is what the X "VESA"
driver supports, a lowest-common-denominator mode so that you can at
least set the resolution correctly on pretty much any video card
today.<br>
