How to install NVidia 7600GT?

[Eldarion]

Hello Forum!
I just got Leo4allv4.1 working on my PC (specs see in signature) but have one question, i hope i get some help here in this Forum...

So, Sound & LAN ist working great, but i don't know how to install my Graphics Card (NVidia GeForce 7600GT 256MB PCIe) correctly.

At the Installation of OSX i didn't select any Driver for the Graphics Card, but i have now installed the NVKush Installer. After reboot there didn't change anything! So maybe there is a special way to "activate" the Driver?

Here's a screenshot of my Monitor Pane:


It would be a great help if someone could tell me what to do... i searched through half the internet the whole day and didn't found any solutions.
