Yes, but the new docking stuff do not base on ibm-acpi. As they handle
the acpi and pci-hotplugging stuff on their own, i hope we don't run
into this limitation again. ACPI should really know about a new
inserted device, as windows can handle this.

But i'm not firm with the ibm-acpi code either with the new docking
driver so perhaps i_m wrong.
