No luck.

I did the steps required for installation and nothing seemed to take place. I'm getting a little frustrated =[.

This is what I have under Display Adapters:
Mobile Intel(R) 4 Series Express Chipset Family.

I've done some research online and found no current kexts for this driver. My question is this:
There are several people stating that they need that same driver. Yet, their only reasoning for needing it is that they can't open certain programs, not that their Hackbook is laggy as hell. It makes me ask, is my video driver really my problem?
