AFAIK you can't have dual head - you'll two different X servers over
xinerama.

E.g.

Section "Screen"
	Identifier  "Screen0"
	Device      "Videocard0"
	Monitor     "CRT0"
	DefaultDepth    24
	SubSection "Display"
		Depth       24
		Modes       ...
	EndSubSection
EndSection

Section "Screen"
	Identifier  "Screen1"
	Device      "Videocard1"
	Monitor     "CRT1"
	DefaultDepth    8
	SubSection "Display"
		Depth       8
		Modes       ...
	EndSubSection
EndSection

Section "ServerLayout"
	...
	Screen      0           "Screen0"
	Screen      1           "Screen1" rightOf "Screen0"
EndSection
