Oh yes, indeed. I do a lot of computational number theory, including factoring
large integers, primality proofs on 1000 digit numbers, multi-precision polynomial
arithmetic over finite fields, etc., etc. 

I'd like to see large word and register sizes. i.e. hardware support for 128
bit integer multiplies and divides, etc.
