Display problems with kernel > 2.6.9

[Markus Rothe]

Hi,

I have a problem with my Apple Cinema Display, if I use kernel versions
above 2.6.9. The display is connected through the Apple Display Connector
(ADC) to my G5 and it's ATI Radeon 9600 graphics card. The problem is that
there are many "blue lightnings" all over the display. With blue lightning
I mean a small set of pixels which turn into light blue for about half a
second. This happens both in console mode and if I run Xorg. I've taken
tree screenshots available at [1], [2] and [3].

The screenshots have been taken while runnig kernel-2.6.11, but this
problem occured with all kernels after 2.6.9.
