Just tried blender-2.69-linux-glibc211-x86_64 and it also doesn't give you access to gpu rendering from User Preferences where nvidia 331.49 will. Blame it all on nvidia.

Turns out that there is a new linux kernel module that needs to be loaded.

nvidia_uvm

Reading this nvidia forum thread;

https://devtalk.nvidia.com/default/topic/699610/linux/334-21-driver-returns-999-on-cuinit-cuda-/

pointed out the fact that there was a module. Searching through the advanced options of the nvidia-installer turned up the proper settings. Seems the package manager builds the driver without by default.

Resolved.
