The problem is currently TGSI can't encode (location, index) color shader outputs, So the shader outputs would have to be mapped from a 1 dimensional array to something 2 dimensional, either defining alternate output colors as primary/secondary, or the secondary color as being an array after the primary color outputs. So I checked the hw, and none of it does this, they all report 1 dual source MRT, so I see no reason to make gallium care until someone creates hw that cares.
