S3's horrible opengl drivers

There are so many errors shown by the S3 opengl drivers, in texturing and lighting. It is shocking.
I do all my dev on my laptop w/ S3 Twister crap.

Does anyone know, if someone wrote an open source version. I remember reading some messages on some S3 boards about 3rd party drivers, specifically opengl, that were better. Thanks.
