Need a quick OOo to load? The OOo QuickStarter 2 probably is your answer. The latest version is already compatible with 2.0.x version of OpenOffice.org application. This application will be started when your desktop loads, so you might have a slower boot up, but as the trade off, you will get significant boost time when you want to load one of OpenOffice.org modules (Writer, Calc, Impress, Draw, Math, or Base).
If you don't want to compile it from source code, then you can use pre-compiled binary packages from LinuxPackages. It's build for Slackware 11.0 (just to remind you).
