You have a mux-less system which means the radeon card is not actually
connected to any physical displays as such there is no way for you to switch to
the radeon card with vgaswitcheroo.  In order to support mux-less systems the
xserver needs support for decoupling display and rendering and the drm needs
support for sharing buffers between drivers.  This is a large amount of work
and probably won't happen in the short term.
