Vista trackpad drivers

I am having problem with my trackpad under vista under bootcamp. It just doesn't seem to have the accuracy it does under OSX. It's almost a challenge to click on any small object without the cursor jumping around all over the screen.

Are there any other trackpad drivers I can use? It seems like even the bootcamp drivers under XP had the same jumpiness and inaccuracy problems.

Hopefully someone can recommend something.

Happy Holidays!
