I'm having some trouble getting OpenCL to recognize my 6990 in my setup. The driver build goes smootly, the system sees the card, tools like fglrxinfo and aticonfig also see the cards properly. However, after downloading and setting up the SDK, I have no luck seeing the GPUs. CLinfo is only able to detect my CPU. I've tried the setup across several versions of Ubuntu and with different combos of the driver and SDK, always with the same results. Any suggestions to get this running would be greatly appreciated.
