Xfdesktop with xorg virtual resolution

Sorry let me try explaining this differently...
xorg.conf:
SubSection "Display"
       Viewport   0 0
       Modes   "640x480"
       Depth     24
      Virtual     1024 768
EndSubSection

This is what I did to try and narrow it down somewhat....
from the first terminal I run:
$ X& (it launches fine)
$ export DISPLAY=:0.0
$ xterm (a window manager-less window appears in the top right of the X 
server... if i move the mouse to the edge of the right side of the 
screen, then xterm  scrolls off the left side which is correct)
$ xfdesktop& (now xfdesktop starts but its wallpaper size is only 
640x480 and I cannot scroll off the screen anymore

I'm not saying it changes any display settings it just doesn't seem to 
be compatible with the virtual resolution feature of xorg anymore(at 
least not out of the box and on this setup). I also noticed it starts an 
xfce-mcs-manager process, are you saying this has settings of its own? 
It seems like, however it works, xfdesktop may be getting the wrong 
resolution from X instead of getting the virtual one, its grabbing the 
actual one.
