ACPIPNP originally supports hotplug, but we removed the capability. The
reason is this will cause conflict because some drivers directly use
ACPI. After fixing such drivers, we will reintroduce the capability.

acpiphp can't handle PCI bridge hotplug is another reason. I did some
investigation on how to make docking station work in my T40 before, and
actually made all PCI devices work with a hack. But I'm doing
suspend/resume, so the work is suspended now.

No, acpiphp and ACPIPNP also can't support hot remove.
