OK I've tried only compiling the intel drm on it's own and also the radeon drm
on it's own, both with and without vgaswitcheroo and each of those were tested
chaning the bios options between fixed and dynamic

Only when both are compiled in and vgaswitcheroo enable do I get a quick flash
of a KMS screen before going blank

Intel only goes blank, looks like it is mode setting however

Radeon only doesn't modeset but segfaults unless nomodeset is passed

I'm now running X using the mesa driver :-(

I can live without the power of the Radeon card until xorg or wayland supports
render and display on two GPUs, I just need to know how to force Intel to do
