firewire support for OpenBSD 3.7

Is there firewire support?
I'm thinking of buying a SUNIX firewire card. I want
to connect external hard-disk bays on my hp c360.
There are 2 cards sold around here. Here are the
details presented in the site of the store:
-------
1 SUNIX PCI FIREWIRE
-------
 PCI Local Bus Ver2.2 Compliant
: 3 1394 version A ports
: speed 400/200/100Mbps
: OSes : Win98, WinME, Win2000, WinXP, WinXP
-------------------------------------------------------
2 PCI FIREWIRE 800(1394B) 
-------
protocol:Chipset: TI TSB81BA3 (PHY) and TSB82AA2
(LYNX)
: Bus type: 64-bit PCI
:3 IEEE P1394B (9-pin) ports
Maximum Transfer Rate :  100, 200, 400
και 800Mbps
-------------------------------------------------------
In case i don't by these cards, or if these cards are
not supported, can you post a link with supported
cards or chipsets?
Thanks a lot
