I found on this slide show a talk, given by some AMD fellow, about an OpenCL compiler: http://llvm.org/devmtg/2010-11/ (go down to the movies/slides and watch out for: AMD OpenCL Compiler - Using LLVM to produce a cross-platform heterogeneous compiler tool chain and enjoy). In this talk, only OS X, Windows and Linux are explicitely mentioned. Is there no interest in supporting the *BSD, preferably FreeBSD? As far as I know, the essential backend of this chain will be the AMD graphics card driver with its CAL compiler generating the binary code. Yes, I know, bringing up the 'FreeBSD and HPC / GPGPU-issue' is naiv and maybe boring, but hope is something that can be very persistent ...

This is probably the biggest obstacle - AMD/ATI support for FreeBSD is terrible. Specifically in this case, there is no vendor-supplied driver at all.
