As another data point I have a Panasonic TH-50PX77U 50" plasma running 
as a digital billboard. It is connected by a 50' HDMI cable and the TV 
does not send out a strong enough signal for the video card to receive 
the EDID info. I am running the panel at 1280x720 and here are the 
relevant sections of my xorg.conf (X.org 1.3.0, Ubuntu 7.10):

Section "Monitor"
    Identifier     "PANASONIC TH-50PX77U"
    HorizSync       10.0 - 80.0
    VertRefresh     29.0 - 85.0
    ModeLine       "1280x720" 74.2 1280 1390 1430 1648 720 725 732 752 
+hsync +vsync
    ModeLine       "1366x768_60" 88.0 1366 1424 1704 1816 768 770 782 808
    Option         "DPMS"
EndSection

Section "Device"
    Identifier     "Generic Video Card"
    Driver         "nvidia"
    Option         "AddARGBVisuals" "True"
    Option         "AddARGBGLXVisuals" "True"
    Option         "NoLogo" "True"
    Option         "ConnectedMonitor" "DFP"
    Option         "UseEDID" "FALSE"
    Option         "ExactModeTimingsDVI" "1"
    Option         "ModeValidation" "DFP-0: AllowNon60HzDFPModes, 
NoMaxPClkCheck, NoEdidMaxPClkCheck, AllowInterlacedModes, 
NoMaxSizeCheck, NoVertRefreshCheck, NoHorizSyncCheck, 
NoWidthAlignmentCheck, NoDFPNativeResolutionCheck, NoVirtualSizeCheck"
    Option         "FlatPanelProperties" "Scaling = native"
    Option         "IgnoreDisplayDevices" "TV, CRT"
    Option         "UseEDIDDpi" "0"
    #BusID          "PCI:0:5:0"
EndSection

Section "Screen"
    Identifier     "Default Screen"
    Device         "Generic Video Card"
    Monitor        "PANASONIC TH-50PX77U"
    DefaultDepth    24
    SubSection     "Display"
        Modes      "1280x720_60" "1280x720"
    EndSubSection
EndSection



The ModeValidation section is because the EDID info fails to pass over 
the 50' HDMI cable.

Cheers,
James
