Acer Aspire TimelineX 3820TG

02:00.0 VGA compatible controller [0300]: ATI Technologies Inc Redwood [Radeon HD 5600 Series] [1002:68c1]

I was able to switch off the ATI card with _SB.PCI0.P0P2.PEGP._OFF, thanks to http://linux-hybrid-graphics.blogspot.com/2010/06/more-linux-switchable-methods.html
