Build failure: Nvidia legacy_390 generic.nix:237 is marked as broken, refusing to evaluate.

Steps To Reproduce

Steps to reproduce the behavior:

1. Create nvidia.nix with below content.

{ pkgs, config, libs, ... }:

{

# Enable OpenGL
  hardware.opengl = {
    enable = true;
    driSupport = true;
    driSupport32Bit = true;
  };

  # Load nvidia driver for Xorg and Wayland
  services.xserver.videoDrivers = ["nvidia"];

  hardware.nvidia = {

    # Modesetting is required.
    modesetting.enable = true;

    # Nvidia power management. Experimental, and can cause sleep/suspend to fail.
    powerManagement.enable = false;
    # Fine-grained power management. Turns off GPU when not in use.
    # Experimental and only works on modern Nvidia GPUs (Turing or newer).
    powerManagement.finegrained = false;

    # Use the NVidia open source kernel module (not to be confused with the
    # independent third-party "nouveau" open source driver).
    # Support is limited to the Turing and later architectures. Full list of 
    # supported GPUs is at: 
    # https://github.com/NVIDIA/open-gpu-kernel-modules#compatible-gpus 
    # Only available from driver 515.43.04+
    # Currently alpha-quality/buggy, so false is currently the recommended setting.
    open = false;

    # Enable the Nvidia settings menu,
    # accessible via `nvidia-settings`.
    nvidiaSettings = true;

    # Optionally, you may need to select the appropriate driver version for your specific GPU.
    package = config.boot.kernelPackages.nvidiaPackages.legacy_390;

  };

}

2. add nvidia.nix in imports.
3. run nixos-rebuild switch

Custom error with reason could be better, but it is only marked broken for kernel 6.2 and later, because it's officially out of support by nvidia. You can still use it with 6.1 kernel.
