both GPU, run OpenCL benchmark, no problem.
Latest test:

I read Diablo Readme for GPU vector size, and diablo return opencl worksize 256, and apply it here.
I try use other kernel, seem mining no respond at all, like null?
this one on Catalyst 13.4, OpenCL 1.2
Uh, I think the "-k diakgcn" is a diagnostic kernel that doesn't actually submit any shares.
