We've seen some reasonable speedup (12x) with some matlab code using Jacket. 
It required up-to-the-minute bugfixes/enhancements from Accelereyes to get it 
working though.  Ran into lots of limitations with some other code (sparse 
matrices) that prevented it from being usable.  Have some reports of success 
with gpulib and IDL.
