Can you try booting with radeon.new_pll=0 added to your kernel command line (not at the same time as the radeon.modeset=0 request above) to see if it fixes the issue also?
** Description changed: Binary package hint: xorg As described, the external display shows massive horizontal offsetting (shivering of some sort) between lines. See http://www.youtube.com/watch?v=8Ky9Yk3pNuI The effect on actual legibility of the screen depends on resolution and refresh rate. Tested on two independent T60s by swapping the hard drive.
