I only would send you my 'latest' experience with MesaCVS.
My current CFLAGS looks like:
"CC = gcc -malign-double -mstack-align-double" \
"CFLAGS = -O6 -mk6 -march=k6 -ansi -pedantic -ffast-math -funroll-loops
-fomit-frame-pointer
-DNO_CONST -D_SVID_SOURCE -D_BSD_SOURCE -DSHM -DUSE_X86_ASM
-DUSE_MMX_ASM -DUSE_3DNOW_ASM -DFX -I/usr/X11R6/include -I/usr/include/glide
-I/usr/local/glide/include" \
System:
K6-III 400
DFI P5BV3+ rev B5 (VIA MVP3) 1 MB L3 cache
256 MB
Voodoo3 3000
2.2.10-ac8
glibc-2.1.1
Now, my problems with MesaCVS together with 'VTK' are solved!!!
I found some texture bugs with some 'glut-3.7'
demos.
Have a look at the small wrong shaded/textured squares below.
Here you can see 1 (one) wrong textured square
at the sphere's surface.

Coloring bug, here? All cubes get the wrong color at the top side.
It is always the same color as the
'current' sproingies has.
Last thing, there are some errors with 'normals' in the fxdriver. I
found that with 'view3ds'. Sorry, I can't
send you an image because I saw it only in 'fullscreen' mode with my
V3 3000. 'In window' is not
possible at this time, shit :-)
Software only is OK.
SunWave1>view3ds
3D Studio to OpenGL File Converter
USAGE:
view3ds <filename.3ds> [-t??] [-s] [-f] [-r] [-c] [-x]
-t Turns on edge preservation. Default is a 90 degree
threshold unless you specify something after the -t.
-s Turns on conversion of the model into triangle strips.
This can speed up the rendering speed considerably at
the expense of a longer start-up time for the converter.
STRIPE must be installed for this to work; see the README.
-f Flips the direction of the normals.
-r Reverses the winding of the polygons.
-c Centers the model around (0,0,0). Try this if you start the
program and see nothing but stars.
-x Exports a .BMF file without rendering.

Nice frame rate, or?!
Not a Mesa-3.1 error but maybe a glut-3.7 or opengl_logo.c source code
issue.
The horizontal part of the 'G' letter has swapped normals!?
