Screenshot of Xorg

I've recently bought a Radeon 7000 graphics card - Sapphire Radeon HD 7870 XT.
I enabled glamor in xorg.conf.

The X server fails to start with glamor enabled. For 10 seconds it shows
nothing. I've attached a screenshot taken with my mobile phone after that.
After killing X the monitor turns off as if the GPU is off (probably true).
X works if I disable glamor. However this way I'd be forced to use swrast.
xorg-xserver - 1.13.2
xf86-video-ati - git or 7.1.0 (both tried)
glamor - git or 0.5 (both tried)
libdrm - git or 2.4.42 (both tried)
kernel - git or 3.7.7 (both tried)
mesa - git

weston also fails to start. It just shows a black screen with a white stripe on
top. Killing it returns me to a tty.

I'll attach parts of the kernel log when starting Xorg and weston.</pre>
