Facinating.  Getting back to OpenMP, it is worth mentioning that IBM 
developed an OpenMP implementation for its Cell processor which 
automatically produces code for both the master processor, and the 
specialized cell cores.  Code is also emitted which performs the 
necessary implicit data copies and synchronization.  The compiler 
decides which threads should run on the master and which ones should 
run on the cell cores.  The result runs as one executable program. 
It seems that Intel's Larrabee approach will make this reasonably easy 
to accomplish since it is based on the x86 instruction set.

Both Intel and AMD/ATI will likely go down this path since they are 
primarily CPU companies and want to sell high volumes of product into 
cost-reduced systems.

If compilers will do the heavy lifting in the future, then it is not 
necessary to perform major surgery on lcms in order for it to perform 
much better.
