something like 1-2 megs for normal sized video... if a card has that
little memory, its io is way too slow to play a hi-res movie anyway.
also, it only affects drivers where the buffers are actually in video
memory and double-buffering is supported, i.e. mga/vidix/directx.

imo it's irrelevant and the stuff about vid mem doesn't need to be
documented. the only purpose of -nodouble is for debugging or if you
have a perverse desire to see tearing. :)
