Not HOTPLUG_PCI_PCIE?

With that selected (I see no point in testing this otherwise) *and*
pciehp_force=1, I get -EBUSY when the hotplug slot registration is attempted
and no wireless, bluetooth or hot key reporting; wireless & bluetooth are
switched off at that point (I made sure that they were enabled via BIOS
setup). Without that option, all is fine.

(As usual with my kernel builds, these are built in.)
