Sorry guys, this wasn't a complete xorg-7.3. My distro had a
backward-compatible-abi release in testing. But now I have a shiny new
xorg-server-1.4.

First thing I can tell is, that my second monitor is listed as connected and I
have a working extended screen!

[jan:~]$ xrandr -q
Screen 0: minimum 320 x 200, current 2560 x 800, maximum 2720 x 1700
VGA-0 connected 1280x800+1280+0 (normal left inverted right x axis y axis) 0mm
x 0mm
   1360x768       59.8     60.0
   1280x800       60.0*
   1152x864       60.0
   1280x768       60.0
   1280x720       60.0
   1024x768       60.0
   800x600        60.3
   640x480        59.9
LVDS connected 1280x800+0+0 (normal left inverted right x axis y axis) 0mm x
0mm
   1280x800       60.0*+   60.0
   1280x768       60.0
   1280x720       60.0
   1024x768       60.0
   800x600        60.3
   640x480        59.9
S-video connected (normal left inverted right x axis y axis)
   800x600        59.9 +   60.3


As you can see, the resolution of the second Monitor (VGA-0) isn't 1440x900
(which it should be). I have tested the following resolutions:

[jan:~]$ xrandr --output VGA-0 --mode 1440x900          # becomes 1024x768
xrandr: cannot find mode 1440x900
[jan:~]$ xrandr --output VGA-0 --mode 1360x768          # becomes 1280x768
[jan:~]$ xrandr --output VGA-0 --mode 1280x800          # becomes 1024x768
[jan:~]$ xrandr --output VGA-0 --mode 1152x864          # becomes 1152x870
[jan:~]$ xrandr --output VGA-0 --mode 1280x768          # becomes 1280x768
[jan:~]$ xrandr --output VGA-0 --mode 1280x720          # becomes 1280x720
[...]


These are the log-outputs when I call xrandr:

When I set
        Option  "PanelSize"     "1440x900"
for the second monitor, then X will hang during start. I can only reboot the
machine via <ctrl-alt-del>.
The same happens when I set
        Option  "DDCMode"       "on"
in the Device section.


I attached an updated Xorg.log.0 / xorg.conf

If you need any additional information, I'm on irc.freenode.org #xorg or email
me.
