I have a D600 with 1400x1050 resolution and a clean installation (no upgrade) of Gutsy. The installation generated xorg.conf file didnt contain the DisplaySize 286 214. After adding the line here are my results from the grep and xdpyinfo :
xxxxxx:~$ grep DisplaySize /etc/X11/xorg.conf DisplaySize 286 214
xxxxxx:~$ xdpyinfo | egrep 'dimens|resolu' dimensions: 1400x1050 pixels (370x277 millimeters) resolution: 96x96 dots per inch
