You absolutely need a G4 to run Leopard from what I understand. Luckily you can drop in a G4 ZIF as long as it's 66 MHz bus compatible.

The oldest I've heard is Leopard on a G4 upgraded B&W. It's easier because it's New World. You would need to somehow use XPostFacto, or do whatever XPF does, as well as what the guy did for his B&W, and maybe it would work. If you got it to work though you would be the first.

Leopard must have a G4 to run but it can run on an upgraded beige:

good choice, My Beige G3 AIO runs tiger quite well. Leopard strugles at times on my Digital Audio G4, it would probably bring the Beige G3 (with G4 upgrade) to its knees

G4 Required. The ZIF upgrade will get the system over the line but Apple has removed the kernel extensions for Gossamer and Heathrow so you will still only see a kernel panic.

You can pull the required kernel extensions from the Leopard WWDC previews or possibly from Tiger 10.4.11.

I've been receiving emails about the issue for the past 2 weeks, people wanting Leopard on beige G3's. Sadly it's quite an involved process.

Yeah, I would stick with Tiger on anything slower than a 1GHz G4 - and even then I'd prefer a DP G4, plenty of RAM, and a decent video card.
