I believe the body has to support the AWB flash reporting and that lesser bodies (lower than 1D series) do not have this feature.
I was apparently in error in stating that the AWB reporting was not in lower bodies.
In the EOS Flash Bible:
"Automatic white balance compensation.
"The colour temperature of a flash tube can vary subtly depending on its precise voltage. The more recent Speedlite flash units can monitor power levels and communicate with compatible cameras to compensate automatically for slight variations in colour temperature.
"Camera bodies which support automatic white balance compensation:
"EOS 20D, 20Da, 1D mark II, 1D mark IIN, 1D mark III, 350D/Digital Rebel XT/Kiss Digital N, 5D, 5D mark II, 30D, 40D, 50D, EOS 400D/Rebel XTi Digital/Kiss X Digital, EOS 450D/Digital Rebel XSi/Kiss X2, EOS 500D/Digital Rebel T1i/Kiss X3, EOS 550D/Digital Rebel T2i/Kiss X4, EOS 1000D/Digital Rebel XS/Kiss F, 7D, 1D mark IIN, 1D mark III, 1Ds mark III, 1D mark IV.
