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):

Section "Monitor"
	Identifier	"TV"
	ModeLine	"1366x768" 85.25  1368 1440 1576 1784  768 771 781 798 -hsync
+vsync
	Option		"PreferredMode" "1366x768"
EndSection

Section "Driver"
	...
	option "monitor-TMDS-1" "TV"
EndSection

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

Sadly, true.
