>From /sys/pccard.c:
static int
slot_suspend(void *arg)
{
        struct slot *slt = arg;

        /* This code stolen from pccard_event:card_removed */
        if (slt->state == filled) {
                int s = splhigh();
--->            disable_slot(slt);
                slt->state = suspend;
                splx(s);
                printf("Card disabled, slot %d\n", slt->slotnum);
        }
---->   slt->ctrl->disable(slt);
        return (0);
}

Note the lines I point to. We disable the slot, as well as the
controller at suspend time.  There isn't much more I could disable. :)
