With xf86-video-ati-6.12.1 and the R4xxATOM option enabled, the situation is
now better.
The LVDS now shows a picture, the same as the VGA-0. I can turn on and off LVDS
and VGA-0 independently with xrandr.

Remaining issues:

The VGA-0 is always driven at 1280x800 (the internal panel's resolution), no
matter what I set in xrandr. xrandr even wrongly claims that VGA-0 is running
at a different resolution when in fact it is not.

VGA-0 and LVDS always display the same content. If I change the monitor layout
eg. with xrandr --output VGA-0 --right-of LVDS then both displays show what
LVDS should show.

With R4xxATOM disabled, the situation is the same as before.
