You'll need to construct a modeline on your own then, and then link it
to the DVI output with another monitor section linked to the DVI-1
output (mode line below computed with the 'cvt' program):
ModeLine "1366x768" 85.25 1368 1440 1576 1784 768 771 781 798 -hsync
Option "PreferredMode" "1366x768"
option "monitor-TMDS-1" "TV"

Yup, you can specify a complete mode line for monitors which have
incorrect EDID data.
