I ran OpenCL on an HD 4650 card with no problem.
I am waiting for 10.3 drivers. Those will be out also for notebook and so we should be able to install ATi Stream!
Alternatively, you could use Mobility Modder.
I cannot because I have a dual gpu solution and I require a special version of Catalyst Control Center which I hope will be included in 10.3
Thanks for your reactions.
