Sadly – as has already been reported – the latest NVIDIA 331.13 driver still won’t compile with 3.11 kernels..
I did manage to get it to work, by applying the 3.11-only patch originally created for 325.15..
It would appear that a ‘legal’ patch for 3.12 kernels would be a non-trivial task, but the 3.11 patch is so very simple…
And… Kernel 3.11 has been out for about a month, already!
