    If I got the discussion so far correctly then the PCI-SGI spec does not
    guarantee that there is no posting, but you know that the chipset
    you are using right now doesn't do it.

    The problem with the explanation is that there will be very soon
    chipsets not from Intel that also implement PCI-Express. And also
    even systems with non Intel CPUs that also do PCI-Express and
    mmconfig.

    Did you check with other chipset vendors like Nvidia or VIA too?

    I would like us to not fall into the "all world runs a Intel chipset"
    trap.
