If you are trying to get your APPLE Ipod to work under Linux, check out the great work the guys at GTKPOD are doing. I'm running an IPOD 30GB Photo. Not a glitch yet, and they just updated the software to support the new Nano unit.
Mine is filled with Death Metal. It helps me get fired up for a workout.
I'm running Fedora Core 4. GTKPOD installs without a glitch. I also use the USB interface on the Ipod.
