It's not clear that the reason for the die diet was in order to rush the chip to market. It could just be because of the economies of doing such a big core. P4 was over 200mm2 even with only 256kbytes cache on 0.18um. In fact I think that's more likely, since the die diet must have resulted in some extra work, eg. all the logic for shipping imuls off to the fp unit, schedule them there, and ship them back.
