As far as I know, the current implementation just take any procedural material applyed and render it as a RGB on the UV mapped image.<BR>

What I suggest is a true baking, that will also take into account the lights, shadows, color bleeding and etc. <BR>

As a bonus , that would be specially awesome as it would allow to bake all-around normal maps for your model. There are third party tools that let you create the all-around map, but with Blender you can only create the map as seen from a single point view.
