After I am one of the first (???) Voodoo I/II, Banshee, V3 3000 and latest V5
5500 AGP users and did some debugging, development (little) and I think that
the SLI support will never come. Bill White worked at the tdfx-2-1-SLI-branch
short before 3dfx fade out. I talked with him several times about Glide3
development, reorganization for XFree86 4.x.x and SLI.
I did some of the Glide3 3DNow! acceleration fixing.
There is still one bug remaining.
So if you have some x86 asm skills (I learned on 6502 and 68k...;-) you can
help me out?
Daryll, have you ever got a Glide(3) lib compiled wit DEBUG enabled?
It crash all the time for me. So how can I get a debugable Glide3 lib?
Here comes the gdb output for a 3DNow! enabled Glide3 running on V5 5500
XFree86 DRI mesa-4-0-branch:

I think my next gfx card is one of the ATI Radeon's (maybe 8800).
