Log file for 6.9.0 driver

I have a Lenovo T400 with a "ATI Technologies Inc Mobility Radeon HD 3400
Series rev 0" graphics chip. Usually I boot up with the machine in the dock
(Lenovo Advanced Mini Dock), and use the DVI output there to drive a Samsung
24" display (multi-head via xrandr).

Version 6.9.0 works like a charm (though unaccelerated). However, using any
later version (tested with the 6.9.0.91 and 6.10.0 versions from the Arch
testing repository), when I boot up with the laptop docked all X does is cycle
through uniformly colored full screens on the internal display
(white->red->green->blue->grey->vertical black/white gradient->horizontal
black/white gradient), and the external DVI output is ignored. The same happens
when I boot up undocked, then put the laptop in the dock and use xrandr to
enable the DVI out.

I attach my xorg.conf and logs for both versions for debugging.
