OpenCL on Nvidia Quadro NVS 160M Driver support for Dell E6500 / Nvidia Quadro NVS 160M

I want to run calculations OpenCL on my Dell laptop (Latitude E6500, Win XP). I installed the Open CL SDK but were unable to find any driver to the card that supports OpenCL.
According to the SDK release notes I would need at least driver version 190.68 to run OpenCL.

Is there a way to get my hands on a driver that I can run OpenCL on? Will there be a driver upgrade so that the card will be supported. Or is the card just not equiped to handle OpenCL?
