Brave! I'm really impressed, how you could work out with such an unpolished
work. Congratulations! :)

I think that you have not set the platform in your nixpkgs:

nixpkgs.config.platform = pkgs.platform.sheevaplug;

You also need that in the ~/.nixpkgs/config.nix for normal profiles to install
proper packages.

That will use all the sheevaplug details in building (like kernel
configurations, etc.)
