Hi,

I have exactly same graphic card and scenario. Also hybrid switching 
between radeonhd and gma4500.
It works for me on my intel graphic, but it needs some experiments with
xorg driver options. It doesn't work out of box without custom xorg.conf
I don't know which option is necessary and which is completely useless, 
but you can try following configuration:

Section "Device"
	Identifier  "Card0"
	Option	    "XAANoOffscreenPixmaps"	"true"
	Option	    "ForceEnablePipeA"		"true"
	Option	    "DRI"			"true"
	Option	    "NoDDC"			"true"
	Option	    "EnablePageFlip"		"true"
	Option	    "RenderAccel"		"true"
	Option	    "AccelMethod"		"XAA"
	Option	    "MigrationHeuristic"	"greedy"
	Driver      "intel"
	VendorName  "Intel Corporation"
	BoardName   "Mobile 4 Series Chipset Integrated Graphics Controller"
	BusID       "PCI:0:2:0"
EndSection

..
..

Section "Extensions"
Option "Composite" "Enable"
EndSection

Section "DRI"
Mode 0666
EndSection
