The nvidia driver download for linux will drive that card - there's only one linux driver that works for all nvidia chipsets.
There are many guides to installing those drivers - the binary should work for you, you may need to install kernel headers. Nothing a quick google won't tell you plenty about.
Try the latest release, 5398, first. If you have any problems with that, go down a release or two - I've heard 5398 is flaky, and all it adds is support for newer-generation features that you won't use with a GeForce 2.
You'll have to edit your /etc/X11/XFree86-4.conf (or equivalent) config script to use the new "nvidia" instead of the default "nv" driver. Should be under the "device" section, do man XFree86-4.conf if you're lost.
Are you using kernel 2.6? If so, things get quite a bit more complicated. I can help you through it, though, especially if you're running debian. Just got it up and running myself.
