Dahdi / bri_cpe in asterisk 1.4


i would like to use my card b410p with new driver from dahdi in asterisk 1.4
So if i configure chan_dahdi.conf with bri_cpe, this parameter was not found in code of asterisk. But with asterisk 1.6-beta3 has ok. I have just a question. Asterisk developpement was decided to include this bri_cpe in asterisk 1.4 or not ?

Thanks a lot for answer.
