I had an eMac that Kernel Paniced out of the blue. Word and safari were running, iPod was plugged in but idle.

Here's the panic log. Can anyone make anything of this?

The only things I can make out of that, is that it seems to be firewire related. Does the firewire work Ok, try syncing your ipod to make sure.
