First of all Mandriva's CUDA packages contain libraries for both /usr/
lib and /usr/lib64.

I could get CUDA and OpenCL to work by reading following tutorial
http://reference.wolfram.com/mathematica/CUDALink/tutorial/Setup.html
1 symbolic links
  su
  cd /usr/lib/nvidia-current
  ln -s libnvidia-tls.so.260.19.21 libnvidia-tls.so
  cd /usr/lib
  ln -s nvidia-current/libOpenCL.so libOpenCL.so
2 script mathematica.sh to start Mathematica
  export NVIDIA_DRIVER_LIBRARY_PATH=/usr/lib/nvidia-current/libnvidia-
tls.so
  export CUDA_LIBRARY_PATH=/usr/lib/nvidia-current/libcuda.so
  mathematica
