DirectCompute 4.1 still not working under Mobility Radeon HD 4650

But OpenCL 1.0 is supported and it works

I really don't understand why DirectCompute 10.1 is still not supported under Catalyst for the 4650 mobile series.

The GPU should have CS 4.1 support and OpenCL 1.0 is working.. So why since over 2 years these GPUs are not working under DirectCompute 4.1/4.0?
