This rumor has been floating around for a couple years now. I remember seeing something a long time ago about ClearSpeed. Originally it was ClearSpeed's idea to incorporate their tech into CPU's and systems.
If AMD can license it for a reasonable price and it boosts performance, why not? It has obvious uses in clusters and supercomputing applications.
I embrace it! Although, I'd be much more interested in seeing a Physics co-processor like Ageia's PhysX. Save the add on cards though- i wanna see it on a video card or motherboard.
