Support for OpenCL Extension cl_khr_int64_base_atomics in AMD ATI Radeon HD series

I have ATI Radeon HD 5970 graphics card in my 64 bit CentOS 6.2 system having Intel core i7 processor. I have installed ATI 12.2 drivers and AMD APP SDK 2.6 . I want to use cl_khr_int64_base_atomics(OpenCL 1.1) extension for 64 bit integer computation on my GPU device, but the device does not support it. However, the same extension is supported by CPU device. Can I somehow use 64 bit integers with my GPU device(I am in desperate need of this)? Is there any work-around for the same? Will the coming versions of ATI drivers/AMD SDK support this ? Is this extension supported by any other graphics card?


For details, output of my clinfo command is attached.
