I've made a few other benchmarks and tried to take some screenshots.
Unfortunately vally doesn't include GALLIUM_HUD when i'm taking screenshot's.
As a workaround i've made photos with my mobile. Hope that's ok :)

On a side-note: I've got other kernel msg's with the unchanged kernel. Don't
know if it's relevant but it looks like that:

I don't know if i would get them with the changed kernel as-well, but with my
stable kernel (3.16) i never see such messages.
