The other E6 revision is the DH-E6 revision, which will have a stepping of 00020FF2h (for A64s and Semprons).
No, we don't have a CPUID picture of that yet, because it hasn't shown up yet, but when it does, the CPUID-type programs will spit out "Family, Model, Stepping" numbers of F-F-2 rather than the current F-F-0.
