I've gotten color picking to work using FSAA.  I disable the following before creating the color picking render pass.  I don't know if they are all necessary, but it works.  I haven't run into problems with colors not mapping correctly and I'm not sure if this is even a problem when rendering to textures.  Color picking works great for my framework since I render specific layers (and actors) only when necessary.  This means I can keep a color picking image around that gets tested thousands of times in a second from moving the mouse.  Another thing to keep in mind is if you are rendering in orthographic you must use integer vector points during the color picking rendering pass.
