Let's answer my own post. I finally got around the "No Validated Modes Found 
for 1920x1080" error message.

I added to the "Device" section:
     Option      "ExactModeTimingsDVI" "true"
     Option      "ModeValidation" 
"NoEdidModes,NoEdidDFPMaxSizeCheck,NoMaxSizeCheck,NoDFPNativeResolutionCheck,NoEdidMaxPClkCheck,NoMaxPClkCheck, 
AllowNon60HzDFPModes,NoVertRefreshCheck,NoHorizSyncCheck"

I also needed to add to the "Screen" section:
	Option "ConnectedMonitor"   "DFP"

Otherwise the video card would output to the CRT-0 device instead of DFP-0.

After these changes, X would now accept the 1080p modeline in the "Monitor" 
section:
	ModeLine    "1920x1080" 148.5 1920 2008 2052 2200 1080 1084 1094 1124 +hsync 
+vsync

And in the "Screen" section:
     SubSection "Display"
         Viewport   0 0
         Modes     "1920x1080"
         Depth     24
     EndSubSection
