I'm having to do this for my Sony KDF-60XS955 (an older model RP-LCD
HDTV), whose EDID similarly only reports 1920x540 (1080i) but has a
native panel resolution of 720p. The relevant xorg.conf sections
are:

Section "Device"
        Identifier      "Intel GX3500"
        Driver          "intel"
        Option          "Monitor-HDMI-1"        "Sony KDF-60XS955 HDTV"
        Option          "NoDDC"                 "true"
EndSection

Section "Monitor"
        Identifier      "Sony KDF-60XS955 HDTV"
        Mode "ATSC-720-60p"

                VTimings        720     722     728     750
        EndMode
        Option          "PreferredMode"         "ATSC-720-60p"
        Option          "DPMS"                  "off"
EndSection

Section "Screen"
        Identifier      "Default Screen"
        Device          "Intel GX3500"
        Monitor         "Sony KDF-60XS955 HDTV"
        SubSection "Display"
                Modes           "ATSC-720-60p"
        EndSubSection
EndSection
