Public bug reported:
Binary package hint: xserver-xorg-video-intel
Screen corruption on xrandr --output VGA --mode 1280x1024.
This happens on i855GM in Jaunty.
The highest resolution on the laptop monitor is 1024x768.
The external monitor is detected and I can choose 1280x1024, but when I do, the
display output gets corrupted.
This seems to be very similar to bug #325781
