Default 1080i

I have my 1080i TV hooked up to my mytv box using a hdmi-dvi cable connected to the GeForce 6600. However the video card refuses to work in 1080i. Apparently the TV is sending an EDID signal telling the video card it can't handle 1080i. However disabling EDID mode validation makes it so that no mode is getting validated at all.

Here are the modelines that I found on the gentoo wiki that I'm using:
Code:
       ModeLine        "720p" 73.825 1280 1320 1368 1640 720 722 724 751 +hsync +vsync
       ModeLine "1080i" 74.52 1920 1952 2016 2208 1080 1084 1096 1126 -hsync -vsync interlace
Here is the relevant part of the log file with EDID modes disabled:
