libGL hates my S3 Savage MX with DRI enabled
 
Ok. So, I have this laptop with S3 Savage MX AGP video. After much frustration, I managed to get DRI working with x11-6.8.1 and the dri.sourceforge.net 20041123 snapshot. Upon completing this week-long search for working code, final victory over accelerated video was stolen from me by libGL.

My setup is this:
Micron TransPort Trek 2 U377
PIII 500MHz, 256MB RAM, Intel chipset, S3 Savage MX 16MB AGP video

Slackware 10.0, Linux 2.6.9, x11-6.8.1

It aparently has something to do with 24bit color depth incompatibility. Once X was reduced to 16, i realized a measure of sucess. Now my gears spin like mad. However, this driver is flakey. I would highly recommend folks to avoid any S3 video chips under Linux. There isnt much in the way of drivers for, and S3's website doesnt read like they really care about supporting their older hardware (unlike ATI or nVidia).

I'm still having funky OpenGL performance in some instances (games...). Does this sound like the drivers are simply limited to 16-bit or are there settings i can adjust or libs i can upgrade?
