Bug#670570: Another success story with 6bda7ceda645e838723883d133d614def1511d16

[Jukka Ollila]

I was seeing this too on an Acer Ferrari 1000 laptop with UMS. Xterm
worked fine, trying to start chromium would crash X.

Applying 6bda7ceda645e838723883d133d614def1511d16 on top of
xserver-xorg-video-ati 6.14.4-2 fixes the issue.

FWIW, KMS works (worked) fine except for suspend/resume which fails at
resume similarly to https://bugs.freedesktop.org/show_bug.cgi?id=20478
.
