Mikel has shown how to do this at the dpkg levelMikel has shown how to do this at the dpkg level. In particular, /var/lib/dpkg/info/$packagename.list is created when the package is installed (and not modified afterwards).

If you used the APT tools (which you presumably did since you're concerned about automatically vs manually installed packages), there's a history in /var/log/apt/history.log. As long as it hasn't rotated away, it keeps track of all APT installations, upgrades and removals, with an annotation for packages marked as automatically installed. This is a fairly recent feature, introduced in APT 0.7.26, so in Debian it appeared in squeeze. In Ubuntu, 10.04 has history.log but the automatically-installed annotation is not present until 10.10.
