sorry, I guess I didn't read your mail carefully enough...

I think what you are looking for is /etc/cron.d and the files therein.
Typically, when anacron is installed, there is a file /etc/cron.d/anacron
containing the line

30 7    * * *   root    test -x /usr/sbin/anacron && /usr/sbin/anacron -s                       

which explains the activity around 7 am you see.

The feature that cron is treating the files in /etc/cron.d as extensions
to /etc/crontab is a debian-specific modification of the regular cron
behaviour -- see the section "DEBIAN SPECIFIC" in man cron.

hope that helps now ;)
