It's important to update your BIOS Revision to A04, and for that you need windows (Dell provides the update as a win executable). Once you have it working, get 10.5.2 with a ComboUpdate (look where you know). Then follow this guide:
http://forum.insanelymac.com/index.php?showtopic=110176&st=100# Get Taruga's Patcher...and you will have a fully QE/Ci, sounding, and fast Dell Leopard.
The install may freeze just one minute before ending, just give it some time, or turn it off and reinstalling again (not formatting the drive). I selected the SSE2 system patch (or whatever it is), and i think that's all you need in the installation.
