Pointers? I'll have a "look", too ;-)

Yes, I reported some "floating exception" to Brian after MesaCVS 5.1 come up.
Same stuff (stex3d for example) worked OK with 4.0.4 and 5.0.
Plane old gcc-2.95.3.
Even -mcup=k6 (no athlon, mmx, 3dnow!).
Don't tell me to use GCC-3.2.1/3.3.x and disable MMX/3DNow!.
All the hard work on this gave very nice results before. Even better than SSE
on Athlon/Duron.
So we need the (kernel) asm experts, here?
Something like (s)fence etc?
I'll see if I get some asm for comparison.
Mesa/demos> ./cubemap
MMX cpu detected.
3DNow! cpu detected.
Testing OS support for SSE... yes.
Testing OS support for SSE unmasked exceptions... SIGFPE, yes.
Tests of OS support for SSE passed.
SSE cpu detected.
GL_RENDERER: Mesa X11
GL_REFLECTION_MAP_ARB mode

SPACE - toggle animation
CURSOR KEYS - rotation
m - toggle texgen reflection mode
