Your screen section is the likely culprit, I had similar "dvi going to 
sleep" problems which I finally eradicated with the following screen 
section (note that your metamodes are probably completely different from 
mine):

Section "Screen"
     Identifier     "Screen0"
     Device         "Device0"
     Monitor        "Monitor0"
     DefaultDepth    24
     Option         "IgnoreEDIDChecksum" "CRT"
     Option         "Stereo" "0"
     Option         "metamodes" "2560x1440 +0+0; 1680x1050 +0+0; 
1280x1024 +0+0; 800x600 +0+0; 640x480 +0+0"
     Option         "SLI" "Off"
     Option         "MultiGPU" "Off"
     Option         "BaseMosaic" "off"
     SubSection     "Display"
         Depth       24
     EndSubSection
EndSection
