There are many packages already available for R that enable various bits 
of GPU functionality.

See the section on GPU's in the High Performance Computing task view:

http://cran.r-project.org/web/views/HighPerformanceComputing.html

I would suggest examining their code for working examples.

After you've done that, perhaps the R-SIG-HPC list would be a more 
appropriate place to continue the discussion.
