As much as I like OpenCL, this part of implementation is going to be
hairy, because to build an app that uses OpenCL one needs binary ATi
drivers, binary NVidia drivers or Gallium 3D. Or you would have to
keep a local copy of respective headers (or write your own ones). You
can imagine the kind of fun that packagers will have.

Hi! This is a question I haven't though.

Well, I think your second option is feasible. OpenCL headers are
freely (as in freedom) distributed in the khronos group page
(http://www.khronos.org/registry/cl/). We just have to hope vendors
follow this specification.
Of course, we still need proprietary drivers (libOpenCL.so) in the
runtime until there is an open-source implementation. But I don't know
if this is a problem.

bye!
