I'm having the exact same issues as Passso, except on a slightly newer-gen laptop with i7-3612QM and Radeon 7670M (Thames Pro/Turks/TeraScale 2):

I am getting the exact same results, ie only able to use the CPU GFX. However it's REALLY shit. Audio problems and incredibly fast drop in FPS to the point I have to reboot in a minute. It doesn't matter what kernel I use with the distro packaged MESA and GFX stack, and so I then start using PPA's like oibaf and Padoka to try get some sanity back, but nothing there either. All produce the same results. I'm hoping it's just some kernel module I need to blacklist, because this all used to work well enough until about a year ago.
lsmod |grep -i radeon
So Bridgeman, you're suggesting using the latest spin of Ubuntu as it possibly has the basic building blocks that could now support the 'older' card's that seemingly got nerfed?
I was also dabbling in using the DRI_PRIME method as detailed on Arch, and it sort of worked somewhat when I last tested 6 months+ ago, but apparently this has been included in some of the newer kernels? So I'd need to look in to that again. I'd prefer not to use arch on my laptop however.
