Just to let you know.. The Firewire on the FS range of laptops doesn't have the full amount power output enabled through it.
This limit's you to using only hardware that has it's own power supply with it. iPods, camcorders, digi.cams etc. should all be fine to use with the port, but they won't charge while you are using them.
It's a good idea to make sure that your iPod has enough power left before you attatch it through the Firewire port or else you might find it locking out your system, or even worse, you might start to loose data from the iPod itself.
