If we talk about OpenCL support for GPUs it might be problematic
because it is implemented by graphics driver.
However CPU acceleration "should" work in my opinion.

I tried to grep "No OpenCL devices found" in jumbo sources and this is
not our message.
BTW it is possible to use Intel CPU on AMD OpenCL sdk, Jim might give it a try.
