jockey-gtk does not list Nvidia Geforce Go 6800

[Arun]

Laptop Dell 9300, Geforce Go 6800
Live CD: Hardy Heron RC

jockey-gtk does not list the nvidia card, it shows an empty window.
So could not enable the hardware driver from jockey-gtk.

Warnings when run from command-line:
ubuntu@ubuntu:~$ sudo jockey-gtk
