        I am running Linux, with 2.6.19.1 kernel version, and I have
        been in contact with the intel engineer which maintains the
        pci-express hotplug support. He has specifically determined, and
        Dell has even admitted to me in chat and phone support, that the
        BIOS does not implement the features necessary for the hotplug
        support that the hardware supports.
        
        This is complete Dell, this is not what I wanted when I bought
        the hardware. Sure, maybe XP does work, but that is because it
        does not use the correct method because XP does not natively
        know anything about pci-express. However, Vista specifically
        _does_ use the correct _OSC method in order to hotplug
        pci-express devices (aka many expresscard devices). If you don't
        believe me, go read
        http://www.microsoft.com/whdc/system/bus/pci/BIOS_HotPlugPCIe.mspx which is a very good whitepaper.
