Not much to explain -- not all hardware works, so you either change 
hardware or change to the old stack (which may or may not work).  In 
either case, file a bug report.

This is the entry in pci.ids:

104c  Texas Instruments
   [...]
   8022  TSB43AB22 IEEE-1394a-2000 Controller (PHY/Link)

Using the vendor code (104c) and info2 (8022) to query:

  <http://hardware4linux.info/pci/104c/8022/> gives

a null response, while a query for 
<http://hardware4linux.info/pci/104c/8023/> gets many reports
of success.

What do you get from "dmesg| grep firewire"?  I have a card with
an ALi Corporation M5253 P1394 OHCI 1.1 Controller
that worked with the old stack, but for the new stack I get:

$ dmesg | grep firewire
firewire_ohci: Added fw-ohci device 0000:00:07.4, OHCI version 1.10
firewire_core: created device fw0: GUID 0090e639000005df, S400
firewire_core: phy config: card 0, new root=ffc1, gap_count=5
firewire_core: giving up on config rom for node id ffc0

There have been firewire fixes in many of the recent updates.  They didn't 
help me with the Ali controller, but since I'm using a desktop with 
available PCI slots, it was simple to add an ADS Pyro PCI 64R2 firewire 
card (Texas Instruments TSB43AB23 IEEE-1394a-2000 Controller, info2=8024) 
that works with the new drivers (using 2.6.24.3-50.fc8).
