Myth already supports this.
I have a CRT HDTV. It's 1080i native, but it cuts off a bit of the
picture due to overscan. The menus looked bad in 1080i, so it runs in
720p for the menus, but with a magic modeline to run at 1152x672 inside
a 720p signal. 1080i recordings play at 1080i, and it seems to get the
frame sync correct, as it all looks good (with nVidia drivers).
