Those are harmless. I think fglrx violates the spec here because it isn't
supposed to write anything on successful compilation(Instead it tells me
verbally that the compile was successful). GL_ARB_draw_buffers is actually
supported, but the driver nevertheless complains. I never saw any negative
effect, and the extension indeed works.

No patches to test unfortunately. Unless you want to dig into the code and
start debugging the driver's behavior etc there is nothing you can do
