You forgot to mention on which operating system you are...

I am working on Mageia Linux x86_64 with Mathematica Home Edition 8.0.1

I had to foresee following symbolic links:
cd /usr/lib64/nvidia-current
ln -s
ln -s
cd /usr/lib64
ln -s nvidia-current/

I start Mathematica with following script:
export NVIDIA_DRIVER_LIBRARY_PATH=/usr/lib64/nvidia-current/
export CUDA_LIBRARY_PATH=/usr/lib64/nvidia-current/

This way the CUDADot example from the Documentation Center works.

Hope this helps...

Kind regards,
