You're probably going to have to get an OHCI PCI firewire card.  As 
you've discovered, the B&W G3 uses a PCILynx controller.  In the early 
days of Firewire, there was a bit of evolution in how host controllers 
interacted with the OS and applications.  The result was the OHCI spec. 
  Unfortunately, PCILynx predated all that, and has a different 
controller architecture than OHCI.  This means that it takes extra work 
to get some kinds of software to work with PCILynx controllers, and 
that work hasn't always been done for Linux.  As you've found here, 
dv1394 and video1394 simply assume you have an OHCI controller.

Even under MacOS / MacOS X, where the 1394 driver stacks apparently 
provide a more complete abstraction model to hide whether the 
controller is OHCI or something else, PCILynx doesn't always work quite 
right.

So, in a lot of cases, people just end up buying an OHCI controller.  
Look for ones with a TI chipset if you can.  (PCILynx isn't bad because 
TI made it, it's actually rather good for a 1394 controller of its era. 
  In my experience TI's OHCI chips are quite good.)
