It will work *if* the controller is not plugged into a riser card. We 
have a 7506 that is plugged into a 66MHz slot on a riser card that was 
very flakey until we turned the speed of the slot down to 33MHz. There's 
a tech note on 3ware's site about this (some riser cards are noisy 
enough to mess up the timing).
