Yes and no.

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.

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.
