Not anymore, but if there were no 64 bit machines... Video ram mapping reduces available memory space. Clawing back a few tens of megs of system ram could potentially have been worthwile(1). Supporting a 32 bit colour depth screen at 32,768x32,768 resolution would require 4gb of video ram, leaving 0 bits in the address pool for the rest of the system :) (1)For very, very low values of worthwhile.
