Thanks!!! However, I have one problem with this, what does the driver need
with 4 full screen buffers when I'm only using a 640x480 window? To me, this
seems to be a serious waste of resources. I was able to run in 1152x864x24bpp,
though that may have been me using system memory for the textures (I can't
remember what settings I used because I changed distros while upgrading X). QF
would give me ~18fps at 640x480 with default settings, and 25-30 when I
disabled the skys (they're badly done in QF:/).

Better than it does now :) What's XAA? antialiasing? Hmm, I'm tempted to do
both for now: drop to 1024x768 and hack that (or wait for Gareth's fix),
giving me ~2.8M.
However, shouldn't the buffer size be based on the gl context size rather than
the X screen size? (I know I'm missing much:).
Also, is AGP texturing planned? When? I'm willing to help (though X's build
system makes me want to run and hide after having used auto* for over a year).
THAT would probably be the biggest boon to my system (minus getting a newer
card:P).
Oh, and sorry about that double post. I couldn't see the previous one in my
outbox so I thought I had deleted it instead of sending it.
