I don't think he wants to ignore EDID, but simply have a more
reasonable fall-back when EDID isn't available (such as when the
monitor is powered off).

I'm not sure how to do a fallback either, but in the past I've solved
this problem by running X once, determining the mode X would chose
when the monitor is on and then add the appropriate settings to the
Display and/or Screen xorg.conf sections.  In the past I've patched up
the following (see man xorg.conf for the gory details):

     HorizSync
     VertRefresh
     DisplaySize
     Mode / Modeline
