freebsd-skq/usr.sbin/dumpcis/printcis.c
imp 9948704a0a The original programs that this code was lifted from (pccardd and 
pccardc) parsed data to make decisions about stuff related to card
configuration.

The purely CIS dumping aspect of this program obviates the need for
such parsing.  Save some space and don't parse the data anymore for
configuration purposes.  Just parse it to print an interpreatation of
it.
