In a similar vein to the UHCI, OHCI & EHCI standards for USB host
controllers there is also an OHCI (Open Host Controller Interface)
standard for Firewire host controllers.  As far as I know all vendors
now follow this. Aside from minor quirks this should make things pretty
straightforward.  (OHCI USB & OHCI Firewire standards are very
different, don't be misled by the similar names.)

Be aware that old Firewire controller chips may have a vendor
proprietary interface.  This should only affect adapter cards.  Firewire
on the motherboard is recent enough that all systems should be OHCI
compatible.
