 I was thinking of compiler support, something along the lines of :

http://aggregate.org/SWAR/

 They have some proven performance, ( quite remarkable too ), getting 
almost 1.5 - 2 GFLOPS out of a cpu running somewhere around a gigahertz.

 As you said, a smarter optimisation enabling advanced use of 
instruction sets.
