unblocking the nvidia stack

[Andreas Beckmann]

Hi Graham,

can you take care of unblocking the nvidia stack? Or should I file 
unblock requests (for some of them)?

nvidia-graphics-drivers
nvidia-graphics-drivers-tesla
nidia-open-gpu-kernel-modules
nvidia-modprobe
nvidia-cuda-toolkit
python-pynvml (defines some more constants, corresponds to newer nvml)

(there is a new 525 driver in the queue ... but I'd like to see the CVE 
fixes migrate first)

Andreas
