I used to install a different way. Download the kernel source, compiled it after falko timme kernel compilation howto. Then I download the binary driver from www.nvidia.com,
placed in / directory, used chmod u+x on the downloaded file, and run it. After that I followed the instructions that are found on the manufacturers page. But at least for Nvidia Geforce2 I managed to get X11 work with binary driver only on linux 2.4 kernel this way (at least was not lucky finding a solution on 2.6 kernel). Could be, my card is not fully supported anymore, so down with the binary drivers. I do not need the 3d screen savers and do not play games too much anyway. If you want the cool features, nvidia binary drivers offer, simply use kernel 2.4 if you have a GeForce2 card.
