With that patch, framebuffer takes a while, but comes up! Works!
I can start X11... I get some errors about nouveau module but glxgears 
starts up and doesn't crash.

So definitely some polish is needed, but lots of improvement. I will 
test more.

So indeed MSI detection is problematic and was one of the differences 
over 9.5.
