>Description:
        I wanted to unplug a pcmcia modem card.  Due to the problem in
        PR 39035, I decided to try "drvctl -u pcmcia0" before physically
        removing the card.  It appears that the pcmcia driver doesn't
        support the DRVDETACHDEV ioctl.

>How-To-Repeat:
        $ sudo drvctl -d pcmcia0
        drvctl: DRVDETACHDEV: Not supported
>Fix:
        Implement the necessary support.
