/**
 * Note: There's no cis3 or cis4 reported for NOMATCH / pnpinfo events for
 * pccard.  It's unclear if we actually need that for automatic loading or
 * not.  These strings are informative, according to the standard.  Some Linux
 * drivers match on them, for example.  However, FreeBSD's hardware probing is a
 * little different than Linux, so it turns out we don't need them.  Some cards
 * use CIS3 or CIS4 for a textual representation of the MAC address.  In short,
 * belief that all the entries in Linux don't actually need to be separate there
 * either, but they persist since it's hard to eliminate them and retest on old,
 * possibly rare, hardware.  Despite years of collecting ~300 different PC Cards
 * off E-Bay, I've not been able to find any that need CIS3/CIS4 to select which
 * device attaches.
