After I sent my last message I realized the same thing... though I occasionally hear people talk about removing it (I seriously doubt that will ever happen). I don't even think there's a way to disable type 1 config access on Intel chipsets... So the last patch is ok then, as long as we can find mmconfig space in the first place, but that's a separate problem for another set of patches (ones that seem to be working fairly well now btw).
