That is pretty much a generic config which tells xorg to figure it all 
out by itself. This is why its not happy when no edid info is returned 
by the monitor.The section below tells xorg to ignore the lack of edid 
data and instead use the video modes you have defined in xorg.conf.

Section "Device"
  Identifier    "Configured Video Device"
       Option        "UseEvents"    "true"
       Option        "DPI"    "100x100"
       Option        "AddARGBVisuals"    "1"
       Option        "NoLogo"    "1"
       Option        "ConnectedMonitor"    "CRT"
       Option        "UseEDID"    "FALSE"
       Option        "XvmcUsesTextures"    "TRUE"
      Option        "ExactModeTimingsDVI"    "TRUE"
      Option        "ConnectToAcpid"    "FALSE"
      Vendorname    "All"
      Boardname    "All"
      Driver    "nv"

The  section below should replace your "Screen" section and controls the 
video mode. I have included a couple standard modes but you will need to 
find what modes your monitor likes and change this section.

Section "Screen"
        Identifier      "Default Screen"
        Monitor         "Configured Monitor"
        Device          "Configured Video Device"
        Defaultcolordepth    24
        DefaultDepth    24
        SubSection "Display"
              Depth    24
              Modes        "1024x768"    "800x600"
        EndSubSection
EndSection
