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 :)
