I am using the Blender 3D 2.71 binary downloaded from the official Blender site. It contain precompiled CUDA Kernel (cuda toolkit is not required to be installed). If I run Blender then CUDA is not available under "File > User Preferences > System > Compute Device" . If I run as super user Blender (kdesudo ./blender), then CUDA is available.
Here's a related thread on nvidia devtalk forum (see message #8):
