Nah.. if it's a new computer, it would probably be a bit different software-wise to your old one.. what I suggest is have your new powerbook all factory'ed, connect it to your old computer (ethernet, firewire etc.), and drag the stuff over =P.
If you got software on cd, you may as well reinstall em from scratch.. drag stuff you need from your home folder and appz folder and the /library folder and you should be more or less alright..
