Just updated to NVIDIA driver version 331.49, and it installs and runs OK on Kernel 3.13 (3.13.3) without the need for any patches.

It can be made to work for Kernel 3.14, by editing the previous 3.13/3.14 combo patch mentioned in a previous article, and removing everything except the nv-linux.h portion of the patch.
