I've just created an archive containing the last version of OpenOffice.org (2.1.0) with all the packages already converted for Debian (or any Debian based distro). My little release contains a Bash script that will uninstall your old version of OpenOffice.org and will install the new one, and the Gnome integration, too..
This is not really a big work, but at least you won't need to download the rpm version of OpenOffice.org, convert the rpm with alien, uninstall your old OpenOffice.org packages, and install the new packages.
If you've got comments, put them on this page, but first go get it!
