good question

have a look at

https://bugs.freedesktop.org/show_bug.cgi?id=9758

or put

xrandr --dpi 96 in .xinitrc

or 
pass 
*-dpi 96

*directly to the xserver

for more info have a look at 
http://wiki.archlinux.org/index.php/Xorg#Display_Size.2FDPI
 
it does sound like the server is misinterpreting the ddc information it receives from your monitor, hence the weird screen size earlier
, seem to recall some like this on the xorg list about six months ago, but my memory might be faulty
hope that helps
