Modding INF files.. HELP

I have a lenovo laptop and i need a new video driver for my Geforce Go 6400.

now i tryed searching a bunch but i can only find rly old drivers... and i keep seeing people mentioning taking a new driver and modding the inf so can someone please inlighten me...

(as i have formated and my video is so hurting at the moment with no drivers =( )

Why do you need new drivers?

if nvidia stopped making drivers - new drivers will not offer anything that will improve the card.

you can check out omega drives, but other then that, it isn't as easy as simply open some inf and adding your card to some list i am sure.
