opencl 2.0 borked for the second gpu on a 295x2 ?

I am not able to run the opencl 2.0 samples on a 295x2, for the SVMBinaryTreeSearch, i get an unsupported device error

Hawaii Device ID is 008C0D38

Hawaii Device ID is 039B99E0

Expected Error: Unsupported device! require CL_DEVICE_OPENCL_C_VERSION 2.0 or higher

clinfo.exe says Device OpenCL C version - 2.0 for the first device and 1.2 for the second device.. Both show driver version 1642.5 but with a different opencl version. I am guessing a bug with the driver perhaps?

tested on windows 8.1, omega drivers and 3.0-beta AMD SDK.

Currently, on AMD platforms with multiple GPUs, only one GPU gets reported as OpenCL 2.0 though more than one are OpenCL 2.0 compatible. I guess same is valid for any dual GPU cards like 295x2.
