Build a dedicated cracking processor (Score 1)

Everybody here assumes that you have to use an x86 processor to crack the 2048 bit code. A x86 proc is designed to do all kinds of jobs, right? When you design a proc just to crack such a code, wouldn't it be far more efficient than a x86 proc? Just design a pipeline to do that, than (like Itanium) put 32 pipeline's on one chip, produce 2048 chips, and let them do some maths. Just think you wouldn't 'just design' such a proc... And heck, what would cost it to produce such a thing @ i.e. TSMC? Think lots of more than $100.000 or $200.000...
