Use a plain white texture (pigment rgb 1, diffuse 1).

Note however that this will distort radiosity results; you /need/ the 
final pigment & finish settings for proper computations (unless your 
object happens to be convex, you're using recursion_limit 1, and there 
are no reflective objects in your scene).

If you have an approximation of the final pigment & finish, you can use 
two copies of your object: One plain white one with "no_radiosity 
no_reflection no_shadow", and one with the approximated texture and 
"no_image".
