I can confirm there are still problems with external monitor. I have a
thinkpad T60p with FireGL V5250 (=x1650 Pro).

On Lucid, I would get the shivering on screen. When I upgraded the
kernel on Lucid using the kernel PPA, the shivering went away. However,
if I used an external monitor the system would start to flicker and then
freeze completely after a random amount of time. If I don't use an
external screen, my system is 100% stable.

This week I installed Maverick, hoping the problem would disappear.
However, I got exactly the same behaviour.

The workaround is to put radeon.modeset=0 in GRUB. However, this has its
obvious disadvantages.

Also, a fellow student of mine with a Thinkpad T60 and X1400 has exactly
the same problems in Lucid and Maverick.
