Because Cycles doesn't have texture baking, and I really like using procedural textures, I made this simple setup to render out procedural textures. Could save you a minute or two of setup time, and lots of render time if you're using complex node setups. It could also make a good material library .blend.
Very handy. I always make the baking in Blender Render and then change to Cycles to use it. Take care.
