Could you point at examples, shots, etc.?  Which renderer?  Does mapping 
reduced RayMir values not work properly?  And remember, any dirt on the 
chrome is (in the real world) a different material, which means that 
it's not really any of the mirror color, diffuse color, or specular 
color for the chrome itself.
