Just FYI you can run FGLRX and the radeon driver in tandem, at least with Gentoo, and I presume on other distributions as well. I don't run with the battery very much but if I absolutely need to I can boot up with FGLRX enabled.
I hope you realize that GCN hardware and open source radeon drivers DO NOT WORK unless you enjoy getting a seizure and/or migraine from black boxes flickering all over the screen.
Look, some people need the ability, and the will, to run experimental drivers, especially if it is as cheap as a reboot. Open-Source software needs its testers.
Also, note, that even the "wonderful" nvidia drivers have the following symptoms: tearing, atrocious crash-happy display hot-plugging, if flash crashes whilst playing a video it brings down X due to vdpau. (these was the symptoms of my previous notebook).
Compared to this, stuttering and tearing is quite pleasant.
The reason I joined this topic, is to state my findings on a work-around for KDE & Source users, and later on to state some sample tuning parameters to reduce the effect of the ondemand governor reducing usability. That latter one, I think is applicable to every Linux system, and could maybe help performance of Mesa drivers too? (referring to the ondemand governor significantly reducing performance in Mesa)
If you want it all, I think you need to use the Intel drivers. Unfortunately the only intel card I have is an old netbook, but it works pretty great there.

On my 7850 with 3.9.4 kernel performance all round is greatly improved.
In cgminer I am getting about 15Mh/s more with identical settings as per 13.4 drivers.
In World of Warcraft under wine there as about 10-20fps more on average.
Native games already ran fine before so i am not noticing a difference.
Tearing I was seeing in VLC/Youtube seems to be gone.
Hope you don't mind me asking, but have you noticed improvement in other gaming titles generally under wine with this new driver? I am unable to test at the moment, but will try and test with Skyrim (my bugbear and the only thing keeping a copy of Windows around). Thanks.
