Firstly: wow, that's 12 year old hardware.
Then again, Tux Racer is non-demanding and pre-dates your hardware, so it should in theory work fine.
Support for your GPU is not baked in to current-generation nVidia proprietary drivers.
For your graphics card you'll need to obtain a legacy driver from the 96.43.xx series.
This driver was available in some versions of Ubuntu's restricted archive, but doesn't seem to be included anymore (unless it's been renamed?). You'll probably need to go the route of installing it yourself from nVidia's website:
http://www.nvidia.com/object/unix.html
Installation mainly consists of executing the downloaded file to build the driver, then running nvidia-xconfig to set up X to use the driver. You may find you need dependencies in order to install the driver, but it should let you know about them.

You need to execute it, not open it in a text editor. There are further installation instructions in the link provided. Direct link to readme: http://us.download.nvidia.com/XFree86/Linux-x86_64/96.43.23/README/README.txt – thomasrutter Aug 03 '14 at 23:47
