Cool. I just bought a new laptop yesterday. It has an expresscard slot, which I think is handled as a PCI Express port (or USB 2.0 port, depending on the card that's inserted). > so there will be a long list of methods in the future hotplug pci > driver and pcib driver > SHPC interface .. > ....... > PCIE interface > ....... > compaq interface > ....... > IBM interface .... > ....... > poer interface > ....... Yes. If ExpressCard isn't handled by the PCIe interface, then we'd want to add it to the list as well.
