I have the Ti 500 version of this card, with lspci output
VGA compatible controller: nVidia Corporation NV20 [GeForce3 Ti 500] (rev a3) (prog-if 00 [VGA])
I use nVidia's driver, which you can get from
nVidia's web page. As of recently, the 2.6.x kernels are supported.
Some poking in /etc/XF86Config(-4) is necessary. Graphics acceleration works fine, and with this computer (a P4 1.9 GHz and 1 gig RAM) I get about 2300 FPS.
