 * due to so few drivers existing.
 *
 * For cards with a device_id tuple, a generic name will be used.
 * if there is no device_id, then the 1275 name will be used if possible.
 * The 1275 name is of the form pccardNNNN,MMMM from the manfid tuple.
 * if there is not manfid tuple, an attempt will be made to bind the
 * node to the version_1 strings.
 *
 * In all cases, a "compatible" property is created with a number
