Putting the package in backports is just a workaround. nvidia-modprobe should be automatically installed when you install the nvidia driver. Does it happening currently with new versions of Ubuntu? Otherwise, this is still a big problem for users: http://blenderartists.org/forum/showthread.php?355719-No-Cuda-option

This is important for CUDA users as they would otherwise have to run a workaround script to load the kernel modules and create the device entries. This is documented here: http://developer.download.nvidia.com/compute/cuda/6_5/rel/docs/CUDA_Getting_Started_Linux.pdf -> 4.8 Verification Because of this newer nvidia-graphics-drivers packages (331 and newer) should at least recommend nvidia-modprobe. Furthermore the nvidia- modprobe is not available from xorg-edgers. Utopic includes an nvidia- modprobe package though.
