 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.
