On my Powerbook G4 15" (PowerBook5,2) I was able to mirror my internal
display on an external screen. Therefore I had to install the Debian
Package xserver-xorg instead of using the xfree86 server. Afterwards I
had to make the following modifications of the file /etx/X11/xorg.conf:

Section "Device"
	Identifier	"ATI Radeon 9600"
	Driver		"radeon"
	Screen		0
EndSection

Section "Device"
	Identifier	"ATI Radeon 9600 Card1"
	Driver		"radeon"
	Screen		1
	Option		"AGPFastWrite"	"True"
EndSection

Section "Monitor"
	Identifier	"Generic Monitor"
	Option		"DPMS"
EndSection

Section "Monitor"
	Identifier	"External Monitor"
	Option		"DPMS"
EndSection

Section "Screen"
	Identifier	"Default Screen"
	Device		"ATI Radeon 9600"
	Monitor		"Generic Monitor"
	DefaultDepth	24
	SubSection "Display"
		Depth		24
		Modes		"1280x854" "1280x1024" "1024x768" "800x600"
	EndSubSection
EndSection

Section "Screen"
	Identifier	"External Screen"
	Device		"ATI Radeon 9600 Card1"
	Monitor		"External Monitor"
	DefaultDepth	24
	SubSection "Display"
		Depth		24
		Modes		"1280x1024" "1024x768" "800x600" "1280x854" 
	EndSubSection
EndSection

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

So far I have not been able to get the option xinerama to work, but the
clone mode works perfectly. You just have to restart the x-server.

HTH,

Peter
