whoops, yeah, that option looks like currently broken.  The problem
is, in a randr 1.2 world, when you enable that option, do you want to
ignore the edid on all outputs or just a specific one?  I suppose we
should probably just remove it as there's a better method now.  see
this page for more info:
Basically you specify monitor sections and assign them to outputs.
from there you can add modelines and specify what you want as the
preferred mode in each monitor section.
