The EasiDock 5000 is a CardBus-to-PCI device. Whilst it doesn't conform to any of the other PCI Hotplug standards (it is just a hot-pluggable PCI bus) the code which needed to be written adds the necessary code paths to our PCI bus drivers to back out of bus resource allocations and detach instances cleanly. The patches to do this are currently in my p4 branch of 5.4-RC1. The thing we haven't worked out how to do just yet is how to divide the necessary resources in a strictly hierarchical way.
