LLVM/CLANG and several OpenCL projects: FreeBSD or any *BSD developer involved?

Nvidia freebsd driver has cuda enabled. But you need the sdk to 
compiled c/cuda to lowlevel cuda/asm (don't remember name now) that 
driver executes on the gpu. Afaik nvidia freebsd driver hasn't opencl 
support but this knowledge comes from "i don't use (tm)" opencl, so i 
maybe wrong. The sdk works for Windows, Linux and MacOSX. ATI has 
retired ati-stream and ati-tometal languages and support opencl in 
windows and linux using a llvm private compiler.

Some days ago, a llvm opencl opensource project started (ati's one is 
not opensource)
