No. chan_dahdi is not required for using DAHDI as a timing source.

If you don't need chan_dahdi.so, why do you load it? Look into 'noload'
in modules.conf . Consider not loading modules automatically. Consider
removing modules you don't need from the modules directory (Consider.
Don't just do without considering).

There are in fact a number of other modules you don't need. Specifically
other channel drivers (chan_*). Also look at the various res_* (do you
need mysql/pgsql/odbc/sqlite/whatever? I bet you don't use all of those
together ;-)

Any reason you don't use a newer version (1.6.2.x? A newer 1.6.1.x?)
