Did it again, but with 'cvs -qz3 update -dP -D 2000-10-22'
(rollback to the 22th October)
Works fine.
Linux kernel is 2.4.0-test10-pre5

Will try second time with the new 3DNOw!/SSE stuff.

This sounds great.
Send as much input for testing as you can along to me 'cause I have an AMD 
Athlon T-Bird 900MHz slot A (yes, really slot A:-), here for testing.

I will try the DRI trunk and the latest tdfx-2-1-branch (tdfx-3-0-branch is 
very slow for textures) with my V5 5500 AGP on Q3 and UT 428a.

Should I tell you that I saw astonishing speed with the VTK 
'sphere-bench.tcl' benchmark (tdfx-3-0-branch)?
The single VSA-100 paired with the Athlon T-Bird 900 outperform a GeForce2 on 
a dual PIII 733 (Windows200 and Linux)!!!
Even 3DLabs Oxygen GMX2000 look not that great...

Best results, summary :
  - i686 running Linux 2.4.0-test10-pre5
  - VTK 3.1.2 (rev: 1.668, 2000/10/26 00:02:16)
  - OpenGL
  - Visual is 1280x1024, truecolor/truecolor/24
  - Tcl/Tk 8.0.5
  - window was 400 x 400

BTW When will we see SLI? Couldn't resist :-)
