Bug#412449: xserver-xorg: Michel's patch works fine for me.

[Takashi Matsuo <tmatsuo@shehas.net>]

Package: xserver-xorg
Version: 1:7.1.0-18
Followup-For: Bug #412449


I use Radeon Mobility M6 LY. I had encountered a similar situation.
I usually use two displays(dual head using MergedFB).

On xserver-xorg_1:7.1.0-18, xorg can not find valid mode for CRT2.
And Michel's patch works fine for me.
