I just tried the Centos 5 Live CD on my Thinkpad T41.

It works pretty good but did not recognize my Laptop's
modem or  WiFi (I guess no surprise there).

I do have a CardBus modem that is not a Win-modem
that I could try when I get home.

I did not see anyway to configure a  PPP dialup call.
Is there a way to run kppp or Gnome's equivalent?
