I found this topic:
https://bitcointalk.org/index.php?topic=71366.40

It appears someone is doing it. I don't have a dedicated mining rig, just using my desktop. I figure I might as well use everything I have rather than let it sit idle (computer is running anyway).

I just updated the driver for the Intel HD 4000. Running cgminer -n, I get the output below. It's apparently getting an error trying to get the device ID of the intel GPU. Any ideas on how to get it working?
