I was curious about that already, did that with a 3.16.6 that I think 
just had your revert applied (and using lspci -xxxx to get the dump 
which I assumed would be the same): No changes to 04:00 at all.

Confirmed that this is the case with 3.17 + those patches as well, it's 
showing this at all times:
