Are things any better with my 3.14 branch? http://cgit.freedesktop.org/~agd5f/linux/log/?h=drm-next-3.14

I don't know if this helps, but I tried your branch (at 4a8ee429cab), and it fails different. For some reason it calls itself 3.13-rc4+, and it defaults to dpm=0, I hope these are not a problem. When I enable dpm, the screen doesn't turn off when the radeon module is loaded, but as X starts, the screen goes black with 1px blue vertical lines at every 8th pixel. I tried 3 times, the same result.

I don't have glamor now, when I'll have some time I'll try with it.
