fwohci0@pci0:6:3:0:     class=0x0c0010 card=0x581111c1 chip=0x581111c1  
rev=0x70 hdr=0x00

     device     = 'FW322 1394A PCI PHY/Link Open Host Ctrlr I/F'

This "card" is built onto my motherboard.

Don't laugh, there were no devices attached when the kernel paniced.

I did plug in my 3g iPod and caught a bunch of error messages.  Last  
time I used my iPod on fbsd was probably back a couple years ago when  
6 became STABLE and it worked.  My iPod works fine with iTunes on OSX  
and  with my car's headunit's iPod controller.
