What about the processor though?
All the main builds of Ubuntu and most other Linux distributions are Intel (/AMD/x86/64) only. The Atom is the main processor on the netbooks, so I think they set the requirements that way to make it less confusing for netbook users (although I would suspect it would run fine on Celeron M netbooks like mine).
The issue isn't the Atom requirement but the underlying fact that the official distributions aren't made for PPC anymore. What you would have to do is install a community-managed PPC build of Ubuntu Desktop (I would be fairly shocked if anyone has made a community-managed PPC build of remix, but I'd be happy to be wrong).
Then, after you do that, you would have to manually add in the remix package from the repository in addition to doing any other tweaks to get the PPC build working.
That guide says for wireless internet you need physical access to the router to plug it in to the computer. This would be a problem at college, I wouldn't be able to make a direct connection
What it means is that you (may) need a physical ethernet connection during the setup process. Once you get wireless working, you don't need it anymore. If you
never have access to an ethernet connection, you would have to download all the necessary files manually and cache them on a USB drive or something.
I honestly would not bother... I would recommend as alternatives...
- Put your effort into maximizing Panther or Tiger performance
- Buy more RAM if your computer isn't maxed out
- Buy a more modern computer (I had an iBook G4, no offense, but I sold mine -- incidentally and used the money to buy a netbook -- some two years ago).
