Isn't that one already merged?

I remember the BAR decoding patch did help with at least one
of the original failures (there were multiple ones iirc0) 

If someone points me to all the patches needed or a tree who 
has them all applied I can give it a quick spin on the boxes I have here.
One of the systems where it originally failed I don't have anymore

That would mean it would boot, but anything that uses extended config
space would fail. While not as catastrophic as before I'm not sure
it's that great either. At least there would be still breakage,
but much more subtle ones.
