I gave that a shot.  When I started up X, it gave me my good old
mirrored/cloned display.

I was confused about one part:

I don't see anything in the output (pasted below) that looks like 
Monitor-VGA-0.


Here is my xorg.conf:

Section "Files"
EndSection

Section "Module"
	Load		"glx"

Section "InputDevice"
	Identifier	"Generic Keyboard"
	Driver		"kbd"
	Option		"XkbRules"	"xorg"
	Option		"XkbModel"	"pc105"
	Option		"XkbLayout"	"us"
EndSection

	Option		"CorePointer"
EndSection

Section "Monitor"

	EndSubSection
EndSection

Section "ServerLayout"
         Identifier      "Default Layout"
         Screen          "Default Screen"
         InputDevice     "Generic Keyboard"
         InputDevice     "Configured Mouse"
EndSection

Also, here is the output from xrandr:

Thanks in advance for all the help.
