You should have downloaded the 4363 driver which gives you one file: NVIDIA-Linux-x86-1.0-4363.run
As user root execute that file and follow the instructions it displays:
# sh ./NVIDIA-Linux-x86-1.0-4363.run
This worked for me, but some others reported that the installer was trying to use the standard kernel module instead of the athlon kernel module. If this happens to you try:
# sh ./NVIDIA-Linux-x86-1.0-4363.run --kernel-name=2.4.20-4GB-athlon
In this case you must have the kernel-source module from the SuSE 8.2 distribution installed.
