- Deactivate the card on removal and queue a REMOVAL event for the socket's event thread to finish the detach. - Queue an INSERTION event for the socket's event thread on insertion. Implement a few missing infrastructure pieces to support this. Hot swapping of PCMCIA cards now "works". (Not quite; things like network devices need changes for their respestive subsystems. These changes are coming soon...)
