Its an upgrade but I have removed my ~/.openoffice.org2 directory numerous times over the past few weeks. Did you verify the package 'openoffice.org' is installed and not just that you have hardy installed? It may be that some other package in openoffice.org which is not installed by default (there are many, and they can't all fit on the hardy install cd) is needed to get the address book source to show up.
