cl_amd_fp64 not working on HD6970

building my program using cl_amd_fp64 extension fails on HD6970 (but works on CPU!)

cl_amd_fp64 should be supported by the HD6970, right? When I query the device it returns it as a supported extension. When I try to build a program where I enable that extension by

#pragma OPENCL EXTENSION cl_amd_fp64 : enable

it fails with the error

error: can't enable all OpenCL extensions or unrecognized OpenCL extension

but it works when I build it for the CPU. Any suggestions?
