Yes, the above option added to my original xfree86.conf does make it work
docked, but (of course) then it doesn't work undocked (xorg seems to try
to drive the internal LCD with 1280x1024). It works undocked with LVDS
instead, or without the option.

Yes, it looks like the remaining issue for me: the xserver doesn't
automatically switch between TMDS and LVDS. Any further hint, or is my
last chance to place a bug in bugzilla?
Thanks for your help anyway,
