iMac Crashes after boot - Kernel Panic

Hi there,

My flatscreen iMac has a nasty habit of crashing after a couple of minutes when I start it up. I need to restart it and it would generaly be fine after that. I would appreciate it if someone could help me decipher the panic.log . ( I have a feeling it might be Firewire related)

Thanks !
