how would I install kde 3.5

That's pretty much it. On lucid of course (oops)

Hi,
Here is Kubuntu Trinity Live CD (kde3.5)
https://wiki.kubuntu.org/Kubuntu/Kde3/Lucid

If you are more into PPA repositories, here you go.
https://launchpad.net/~kde3-maintainers/+archive/ppa
https://launchpad.net/~kde3-maintainers/+archive/trinity-svn-nightly

I would recommend downloading and trying out the live cd from the first link though, at least to see if you like it as a live session, because kde3.5 might not be so easy to remove from your existing install.
Hope this helps.
