Adding a patch for grub, so livecds with grub can still boot with buggy bioses,
as those of Acer 292LMi or Airis N990. This allows booting the NixOS ISO releases. I made it optional, not included by default. I don't think it would harm at all enabling it always - let it be decided on forum. svn path=/nixpkgs/trunk/; revision=16341
