Bug#422777: xserver-xorg-video-ati: xcalloc patch worked, confirm

[Daniel <garkein@mailueberfall.de>]

Hello,
just upgraded my xserver-core to 1.3.0.0.dfsg-6 with radeon driver
6.6.3-2 and ran into the same problem.
Googled to this bug and to 
https://bugs.freedesktop.org/show_bug.cgi?id=9816

and can confirm that the xcalloc patch solved the problem.
MergedFB working again. *Please* include that patch quickly into the
debian package.

Thanks,
Daniel
