Well, as an addon, you get 3d acceleration. Even if you don't play
games, you can enjoy opengl screensavers and -vo gl2 driver ;)

No. Well, if you don't need opengl, that's true, you can sacrifice 8M.
But the problem is, it doesn't work. I haven't tested it with current
card & driver, but with my old 8500 and 2.5.1 or 2.9.12 drivers my
computer hung up hard instantly on launch of mplayer or any opengl app
when limiting video memory. I believe it worked a very long time ago and
it works on matrox, but not in this case. Well, it was a dirty solution
anyway. That patch is a hack too, but at least it works without problems
or limitations.
