defaults write org.x.X11 app_to_run "/usr/X11/bin/xterm -geometry +100+100"

adjusting the +100+100 as needed to center, and using something like 100x30+100+100 to adjust size as well as position.

you're right, the solution is: defaults write org.x.X11 app_to_run "/usr/X11/bin/xterm -geometry 140x22+210+0" – juanpablo Mar 14 '10 at 20:03
