i'm sorry, i made a mistake. the 5346 driver is a non-nvidia release by pny.com for the quadro FX, but seems to be working with the GeForce FX as well.
i found out about it on gooeylinux.org
which will point you to nvnews.net
where you can see screenshots of people using their GeForce FX cards. the driver is available on pny.com
