I wouldnt be suprised if the G3's are canned from 10.5. If they are, upgrade to a Intel Mac.
They're not going to can all G3s, since a lot of relatively recent iBooks use them. I wouldn't be that surprised to see an AGP requirement to knock the B&Ws and early iMacs off the bottom, though. Then again, there's a good chance that you'll be able to get it to install and run just fine with a program like
XPostFactor that allows install on unsupported systems. Remember there are people running OSX on ancient 9500s, and 10.3 (and 10.4, I think) can be installed on beige G3s using this.
It's also worth noting that from some stuff I read, Apple has finally firmed up the core OS APIs with 10.4, so there will be less apps that require the latest OS to run properly. That is, up until now they've been in serious flux, so every new version of the OS added a bunch of features that programmers could take advantage of, but would not be available on earlier OS versions. That is, at least in THEORY (perhaps not in practice), not going to happen as much now--programs will generally be more flexible with backward compatibility.
And remember, even now almost everything runs on at least 10.3, and a lot of stuff still runs on 10.2.
