BOINC does not appear to be ready to allow OpenCL workunits for any GPUs other than those from AMD/ATI and Nvidia. OpenCL is meant to be hardware-independent, but BOINC's interface to OpenCL GPUs definitely isn't.

The 7.x boinc client version has made enormous strides on OpenCl support (see Albert@home for example).
Now, it's up to the projects.....
