the 12-6 non-beta drivers properly recognize this device and gpu switching seems to work. Weeeee! Now if only I could switch without restarting x, and get all the speakers to work ... :)
Nonetheless -- AMD takes a lot of crap in this forum, but it's only been a week or so since this machine was released, we've already got driver support, and the HDMI out works which is more than I can say for any optimus laptop. I can see why I'd pick a nvidia chip for a desktop, but for a laptop the pickings are slim and AMD's the only fully functional option.
