Baja, do yourself a favor and look into broadband. It's only a little more expensive than AOL, but a lot faster. Once you set it up, all you would do under Knoppix is to click the Mozilla icon (looks like a tyrannosaurus) - you're there. You will love it.

If you insist on dial-up, I noticed that NetZero has a client for Lindows. Maybe it would work (but I don't recommend it).
