Yes. Switching to discrete graphics in the BIOS works fine. Make sure you have the ati and radeonhd drivers installed - works fine. It even works if I leave on 'OS detection' and 'switchable graphics' (I forget to change the option sometimes). Although it does get mighty hot, I don't believe the GPU thermal management driver is very good, as both GPUs are running.
