(copied to linux-kernel and Martin Mares, Linux PCI maintainer)
Since 2.2.x stuff like this have been handled in the generic PCI layer,
not on a per-driver basis. (though 2.2.x doesn't cover nearly all the
PCI-related stuff that 2.3.x does, especially WRT PM and hotplug)
Would someone be up to submitting a patch to the kernel which notices
and corrects for this behavior for the general case?
