I'm running a multiseat setup with 2 radeon (ATI3650HD and ATI5450HD) and 1
intel cpus, I'm using libdrm, mesa and xf86-video-ati from git on gentoo.

I'm syncing with the repos every thursday, yesterday I've syned with the repos
and after boot today, all the screens connected to radeon are black.

in the sync last thursday everything worked ok, also when downgrading to
xf86-video-ati-6.14.6, the system works.

when observing the commit logs on xf86-video-ati of this timeframe, the only
commit is enabling 2D tiling.</pre>
