On SO you give and take information, and so far you've only been taking. How about giving something back to the people who helped you? – Niklas Sep 25 '12 at 11:36

Those dialogs are a part of debconf which is a configuration tool for Debian packages. It has many front-ends, ncurses is one of them.
You can use dpkg-reconfigure -f noninteractive, use debconf's Bash library, reconfigure debconf itself to be always non-interactive, etc.
And there's also a package called debconf-utils:
This package contains some small utilities to aid users and developers. There are utilities to help manage debconf databases, others to manage translated template files and a program to communicate directly with debconf from the command line.
