It might (or might not) be a bad idea, but we simply do not have the
manpower to deal with the vast flow of new video cards that arrive
with time. We have to use the drivers because by doing that, we
get to piggyback on all their manpower. Unless you have a way to fix
that problem, even if the current system sucks rocks, we'll have to
continue using it.
