add 1600x1200 to your screen section:

Section "Screen"
	Identifier  "Screen 1"
	Device      "device1"
	Monitor     "monitor1"
	DefaultDepth 24

	Subsection "Display"
		Depth       24
		Modes       "1600x1200" "1024x768" "1600x1200" "800x600"
		ViewPort    0 0
	EndSubsection
EndSection

even though crtc1 won't use it, mergedfb uses these modes as it's mode
pool.  Also for flexability you may want to add some other modes to
your metamodes.  Then you can use  xrandr to switch between then.
