Do you have anything that isn't a baseless handwaving rant to back that up?My only reason for slightly doubting it is that there is so much discussion about using different CPU frequency governors. Of course, most people can be dead-wrong about many things.
The same issues occur even when changing the address in rc.multi. I just tested it to be sure. I should have mentioned that I have also tried changing the MAC address with net-profile's PRE_UP command.
