hmm. that's not much help either. can u recompile evas with full gdb debugging?
ie:

make clean distclean
export CFGLAGS="-g"
./configure
make
make install

it might not help much either if the stack is screwed though...
but warning:
1. 3dfx doesn't support 24/32bpp textures. evas will look like a dog's festering
maggot-ridden rear end with 16/12bpp textures, which is what opengl will have to
fall back to. trust me. i can see it here on this i810 - its god-awful. i
wouldn't want my most hated enemies be subjected to this pain.
2. 3dfx has maximum texture sizes of 256x256. given the opengl engine this means
any images greater than 26pixels in any direction simply will not display. u
will get a "white box" instead.
3. get a new card. an ati or nvidia card is dirt stinking cheap (the lower
enough ones) and will run RINGS around your 3dfx card in quality, performance
even at the $50-100 card level.
