Nothing so elaborate. IIRC the reason for it to be a 933 is that Motorola couldn't deliver any 800MHz. Eyetech sold him 800, not more.. if he would have raised the spec now, what would the hundreds of people that already bought 800 think/say? He paid for 800, he got 800..
There's a whole article about it, written by Alan in Total Amiga.. this or the previous issue. Go look it up, it's in there.
