You don't really need it.

If this is Asterisk 1.4: Is chan_dahdi built to use dahdi or zaptel?

Compare the following two:
  strings /usr/lib/asterisk/modules/chan_dahdi.so | grep dahdi
  strings /usr/lib/asterisk/modules/chan_dahdi.so | grep zaptel

Also, what is the output of:

  cat /proc/dahdi/*

No, you should use dahdi_cfg
