Actually the TV mode and margin setting is already exposed in KMS,
as you can see from your xrandr --verbose below. So changing with output
property should work for you.

The only thing left is to keep on recognizing the xorg.conf option in KMS.
It should be easy to be fixed. And we might check if there's any other origin
options need to be taken care for KMS.
