You would have to build device firewire # FireWire bus code device dcons_crom device dcons into the kernel -- attempt to load them as modules had DDB complaining about the lack of suitable ports. Again: it definitely works on my built-in Firewire, and I am pretty much sure it used to work on the card. Unfortunately, I do not have cards handy to check it right now. -- Alexandre "Sunny" Kovalenko
