CUDA Driver installation failed with NVIDIA card for Sony cuda driver installation failure, NVIDA fo

I have this laptop computer: Sony VGN-AW41ZF/B. If I install CUDA Toolkit 4.0 driver: “Notebook Developer Drivers for WinVista and Win7 (270.28)” I get an error message: “This graphics drivers could not find compatible graphics hardware” and it fails. My graphic card is: NVIDIA® GeForce® 9600M GT GPU. This is compatible with cuda. The problem might be that this graphic card is done by NVIDIA for Sony and the Sony driver might not be ok for CUDA toolkit. Is there any way to to get this working or go around solution. Thank you.
