I have the same card. One of my monitors doesn't send EDID and this config works
for me:

Section "Monitor"
        Identifier      "E481"
        Option          "LeftOf"        "H481"
        Option          "IgnoreEDID"    "on"
        Option          "DPMS"
        modeline        "1280x1024 at lcd" 108 1280 1326 1440 1688 1024 1025 1028 1066
