DisplaySize in xorg not working (ATI catalyst drivers)

Question

In xorg.conf I have "DIsplaySize 364 273". But when I start X xdpyinfo reports the dimensions as "338x253 millimeters" (which happens to be 96x96dpi @ 1280x960).
The only relevant line I can find in Xorg.0.log is:
[ 1230.917] (II) fglrx(0): Setting screen physical size to 338 x 253
Here is my xorg.conf:

hey LukynZ,
thanks for the hint. I tried it but didn't work. Same situation as before... Would some specific output be helpful?

You can try the patched xorg using the catalyst repository as per the wiki, might fix things up.
Hey Snakeye,
also thanks to you! Well, the problem is, I cannot even click on Advanced because everything under "System Settings -> Desktop Effects" is grayed out. See yourself:
Anybody got an idea? I would really like to get this working... :-/
Thanks for all your help so far!
