Xorg is smart enough to autogenerate its own modelines on demand if given the 
right framework within which to work as a substitute for EDID or to override 
it. All xorg.conf needs are skeleton Screen, Device and Monitor sections, 
with HorizSync and VertRefresh specified. If this fails to permit 1152x864 by 
default, then add 'Option "PreferredMode" "1152x864"' to Section Monitor. My 
G41 responds to such setup perfectly with a variety of displays.

If your distro provides a skeleton file set in /etc/X11/xorg.conf.d/ you can 
use them instead of xorg.conf.
