I have an AMD k6-3 CPU and an old ATI mach64 video card. I compiled mesa-6.5.1-r1 and xorg-server-1.1.1-r5 with gcc-4.1.1-r3 with -march=k6-3. I have the kernel mach64 driver loaded and glxgears works. glxgears works, but when I try to run a game like tuxkart I get "Illegal Instruction" and the game aborts before it even loads.

Has this ever worked for you? Try rebuilding mesa, xorg-server and your video driver with -O2 instead of -Os and see if that helps.
This game hasn't worked for me on that system yet, until now with mmx disabled. I recompiled with -O2 -g, debug and nostrip. I found that the game starts up if I $ export MESA_NO_MMX= . If I don't it gives me illegal instruction. With the default settings, here is what gdb says when it crases: Program received signal SIGILL, Illegal instruction.

Can you try mesa 6.5.3 and report back? Please reopen when you reply.
