Thanks for sharing. I will contribute my findings as needed. BTW, do you 
need my VBIOS loading patches (sent long time ago) for AMD GPU? It is a 
dilemma for several reasons:  it doesn't always work; sometimes it can 
screw up main display while passthru 2nd GPUs. Plus the recent Catalyst 
driver seems very stable even without these patches. But Wei Wang told 
me that he needs them for some of his cards.
