NixOS configuration for running NVIDIA GTX 750 Ti (Maxwell) with driver 580.142.

Newer NVIDIA drivers (e.g. 595+) silently drop or break support for older GPUs like Maxwell, causing errors such as:

modprobe nvidia → No such device

This configuration pins a working driver version using mkDriver, disables GSP (not supported on Maxwell), and provides all required hashes.

Tested on NixOS with flakes.

Useful for anyone trying to keep older NVIDIA GPUs working on a modern NixOS system without downgrading the entire nixpkgs.
