Hmm, on a quick smoke test with both patch series (mine + igors) applied
everything seems to work fine on a quick glance.  Dunno why.  Maybe the
pcieport driver turns on slot power even in case pciehp is not active.

I still feel a bit nervous about trying the new "both pcie + acpi
hotplug enabled" approach that close to the release date ...

take care,
  Gerd
