It has been years since I looked at MCP quirks, of which there are too
many.  It's likely another quirk on the controller side that nvidia
worked around somehow without telling anyone.  Given the history and
that nvidia is out of chipset market, I think it's highly unlikely to
learn what the issue and workaround are without reverse engineering
it.  So, um, no idea.

Thanks.
