double precision clAmdFft on Cayman?

I find I am unable to use double-precision ffts with this package on a Cayman GPU, however it works fine on my CPU.

 

Is this because Cayman only supports cl_amd_fp64 and not cl_khr_fp64? clAmdFftBakePlan returns CLFFT_DEVICE_NO_DOUBLE (Double precision not supported on this device.)
