In case that's a response to my question above:
If minator is right and the devkits really have the PowerEN chip then they simply do not have VMX128 or standard AltiVec/VMX. How would it be added to the existing devkits? And assuming that was possible, how would the developers program for VMX128 as long as it has not been added to the devkits?
