Bug#405998: [xserver-xorg-video-mga]: xv video is blue after kernel suspend

[Helmut Toplitzer <bgrpt@toplitzer.net>]

Package: xserver-xorg-video-mga
Version: 1:1.4.4.dfsg.1-2

Playing a video on a mga multihead/xinerama setup
is working without problems (using X11/xv).
After suspending the system (kernel suspend) and
resuming the only output on the screen is a blue box.

I tried resetting the colorkey with
xvattr -a XV_COLORKEY -v 66046 
but it didn't worked.

Logging out of the X session and logging in again 
solves the problem. 

Attached you'll find the xorg.conf
