Actually I can't use my HD 7950 with KDE becuase of

https://bugs.freedesktop.org/show_bug.cgi?id=69341
https://bugs.freedesktop.org/show_bug.cgi?id=64297

so I attached my display the Intel HD 4000.

I still do bitcoin mining (OpenCL) on the 7950 and I notice it doesn't switch
to higher power states anymore (everything works flawlessly if I attach the
display to the 7950). Forcing the card to the lowest power state if no display
is attached is a bad behavious because of GPGPU computing.

I'm using Linux 3.12-pre (drm-next).
