I'd recommend you to use the following lines instead of what I've
quoted.  The reason is that the "pkgs" attribute that you are creating
may not be the same as the one used by the other modules.  This may
cause extra work and extra package duplication/compilation.

------
{pkgs, ...}:

let
  kernelPackages = pkgs.kernelPackages_2_6_28;
in
------

Cheers,
