I have checked in the first 40% of the PIII-optimized vertex-transformation code. It can be optimized more (using prefetch-instructions to prevent cache-misses)... I have modified the configure.in file and the file src/X86/Makefile.am to enable the use of the new PIII-assembly in autoconf/automake. I have also modified the files Makefile.X11 and Make-config and added the make-options "linux-katmai" and "linux-katmai-glide". If you want to test the new PIII-vertex-transformation code remember to install the kernel patch from "http://people.redhat.com/dledford/linux_kernel.html" !
