You have a muxless powerxpress system so there are no displays physically
connected to the radeon card. The only way to utilize the radeon card is for
offscreen rendering (radeon renders application frame and the frame is copied
to the intel card for display). You need the new gpu hotplug features in
xserver 1.13.x or 1.14 to utilize the card in that manner.
