Intel doesn't provide any OpenCL SDK.  There is no way to "program" the GPU.
That's untrue, starting with sandy bridge and up Intel's IGP supports OpenCL.
Their SDK can be downloaded from here:

Do you read before you claim things are untrue....

See any GPU in there?  Intel has long supported OpenCL on CPU ONLY.  I will wait for your retraction.  If you still don't believe me install the SDK and try to run the samples on an Intel GPU.  No need for a miner to prove it is possible just use their samples.

No intel GPU to date supports OpenCL.  No ifs, and, or buts.  That may change in the future but given the lackluster performance I doubt Intel wants a direct comparison.  They would much rather companies buying $8,000 server CPUs.
I could be wrong here but i think HD graphics is embedded into all of those chips.
