I did this long time ago for a monitor with a long cable, long enough to 
make EDID fail. The solution was to add a modeline to xorg.conf, in my 
case it looks like this (mind the email linebreaks). It still works.

Section "Monitor"
     Identifier     "Monitor0"
     VendorName     "IBM"
     ModelName      "ThinkVision L190"
     HorizSync       15.0 - 70.0
     VertRefresh     58.0 - 64.0
     ModeLine     "1280x1024_60.00" 108.9 1280 1360 1496 1712 1024 1025 
1028 1060 -hsync +vsync
     Option         "DPMS"
EndSection


Part of this lesson was that a cable can work in the video sense while 
still not having bandwidth enough for EDID.

OTOH, perhaps you're right :)
