He had a 3 module unit. One module was completely dead and had to be disconnected or it wouldn't fire up. One module would overheat and trip the code that disables it almost immediately unless it was run at 20% speed. The final module ran stable at ~420GH.
This is worse than I thought. Now we know yet another reason for them not to ship - they certainly don't have a working product. Keep in mind that this unit was one of the last ones assembled just before the New years eve, so this was not the previous "experimental" product. This also explains why they've sent LukeJr unit to him in a hurry, in an insane hope there's something code realtead bfgminer can do which cgminer can't.
