Yeah I was mainly concerned with the Ethernet. This is the Abit NF7-M, and there is only one ethernet on it. What I did was fairly simple. I installed Mandrake 9.1, I then installled the linux kernel source. This was a file named kernel-source-2.4.21-0.13mdk.i586.rpm
After installing the kernel source files, I simply unpacked the tar file from NVidia, then did make, make install, and finally updated the modules.conf file as described in the installation instructions.
