For whatever reason DDC tends to be unreliable on XPRESS chips.    I
think it may be a clock issue.  Without DDC, the server is not able to
find any modes for the output.  you'll have to add a monitor section
and link it with the output in question.  see this page for more:
http://www.intellinuxgraphics.org/dualhead.html
then add modelines for your monitor
something like:

Section "Device"
	Identifier	"ATI Technologies Inc RS480 [Radeon Xpress 200G Series]"
	Driver		"radeon"
	Option "DRI" "false"
	BusID		"PCI:1:5:0"
	#Option "Monitor-LVDS" "Generic Monitor"
	Option "ConnectorTable" "5,2,1,4,5,1,2,2"
        Option "monitor-DVI-0" "Generic Monitor"
EndSection

Section "Monitor"
	Identifier	"Generic Monitor"
	Option		"DPMS"
        Option "Enable"  "TRUE"
	HorizSync	30-100
	VertRefresh	50-61
Modeline "1280x1024"  109.00  1280 1368 1496 1712  1024 1027 1034 1063
-hsync +vsync
EndSection
