Just posting a little progress if anyone is interested. Using the program at
http://analogbit.com/node/23 I was able to modify the edid.bin and load it,
get a correct picture and sound using the modelines that were supplied

   ModeLine   "1920x1080" 148.500 1920 2008 2052 2200 1080 1084 1089  1125
+hsync +vsync
   ModeLine   "1280x720" 74.250 1280 1390 1430 1650 720 725 730 750 +hsync
+vsync
   ModeLine   "720x480" 27.000 720 736 798 858 480 489 495 525 -hsync -vsync

But I'm having some odd problems, Rythmbox hangs the machine and ultimately
needs a reboot - it worked fine when EDID was disabled totally.

Also, what are all these options for and are they all needed?

   Option      "ModeValidation" "AllowNon60HzDFPModes, NoVESAModes,
NoXServerModes
   Option         "RenderAccel" "true"
   Option         "DynamicTwinView" "False"
   Option         "TVOverScan" "0.00000"
   Option         "AllowGLXWithComposite" "true"
   Option         "NoLogo"
   Option         "XvmcUsesTextures"  "false"
   Option         "UseEvents" "True"
