Which version of Ubuntu should I use on an old iBook G3 (PowerPC)

[NewsAndHistory]

Would any of you please tell me which version of Ubuntu (ie: the latest version of Xubuntu, Kubuntu...ect) would work best on an Apple iBook OS X Panther (Processor: 600 MHz - PowerPC G3)? Should I use XFCE or Flubox since I don't have a lot of RAM (256mb)?

I'd like my iBook to be able to use the latest version of Adobe Flash, but my iBook won't do so as long as I'm using Panther 10.3 OS X. Ubuntu seems to be more compatible with Web 2.0 than Panther 10.4 OS X, so that's why I want to overwrite it with a fresh installation of Ubuntu.

Thanks in advance. If you would like to suggest any other well-known Linux distros* to install on any old non-intel iBooks PPC, (*distros such as like Slackintosh, Mint 6 XFCE, or Fedora 6 or 10) please tell me so.

I should install Xubuntu. But if you are experienced in Linux you shoud install ArchLinux, thats pretty fast but dificult to use.

You'll want a ppc compatible version of Ubuntu (I'd go with Xubuntu with ur hardware specs) which can be found here...

Thanks for helping me. Arch Linux seems like a challenge worth taking, when or if I become less ignorant & impatient with setting up operating systems.
