27  * PCMCIA NEXUS
28  *	The PCMCIA module is a generalized interface for

30  *	the logical socket name space while allowing multiple
31  *	instances of the hardware to be properly represented
32  *	in the device tree.
33  *
34  *	The nexus also exports events to an event manager
35  *	driver if it has registered.
