I believe that a lot of the "devil's advocates" for non OSS drivers are wrongly equating OSS with (L)GPL'd software. Many in the community (such as myself) would be hapy if they printed out the code, took a black magic marker to the IP protected stuff, and scanned the resulting docs into a PDF. They could claim full copyright and people would still continue to contribute and make suggestions. They call it the "Open-Whoop-Dee-Doo" license.
Heck, at least the modline problems, Xv bluescreen, and 2D rendering speed problems would have been fixed by now (I have not yet tested the 5336 drivers to see if these problems still exist). We'd probably have overscan working for TV-out on older models as well.
Personally, I could care less if they OSS their drivers. I have one monitor, and don't use TVOUT. If NWN runs, and my pr0n doesn't jump around in Mplayer, I couldn't be happier.
Thank you for your time,
