Can you expand on why the resource should be non-posted?  I didn't think
non-posted was a requirement of pci config space.

Where are you configuring posted vs non-posted behavior?

Do writes to extended pci config space actually work for you.  A
coworker hacked something like this together a while ago for one of the
boards we support and there is a bug where I can read extended pcie
config space but not write to it.  Except for a bit of trivial looking
I haven't had a chance to dig into that problem.
