Does anyone know if ATI is working on allowing more than 256 mb of Global Memory for Radeon 5870 in future drivers? Why do they allow only one UAV currently at 256 mb?

Currently the global memory available is the value returned by CL_DEVICE_GLOBAL_MEM_SIZE in device query. Full physical memory is expected to be available in one of the upcoming releases.
