Created an attachment (id=35874)
 --> (https://bugs.freedesktop.org/attachment.cgi?id=35874)
dmesg info and xorg.log

dmesg output and Xorg.log with all default stuff in the attachment. With that I
get the flickering.

I've taken another look and it's more like the screen flickers between black
and normal display when it flickers. No vsync thing as I mentioned earlier.

I've added radeon.modeset=0 and it looks like this has removed the flickering
entirely, so I'm happy (I don't really need KMS on that box).

The radeonhd driver (from Ubuntu 10.04 lucid repositories, same place where I
got radeon) also flickers, but a lot less.
