I also had to specify "-lpci" on Mandrake 10.1, "-lpci -lz" on Gentoo.

These are both VT6306, one on the motherboard and one on a PCI card.

On another PC:

	# lspci | grep 1394

	IEEE-1394b Link Layer Controller (rev 01)

	Host Controller (rev 80)
	06:00.0 FireWire (IEEE 1394): VIA Technologies, Inc. IEEE 1394
	Host Controller (rev 46)

The "rev 80" chip is a VT6307 on the motherboard.

	# ./a.out 05:04.0

	Your VT6307 chip is in OHCI 1.1 mode

The "rev 46" chip is on a CardBus card.  So far I believed it to be a
VT6306 but I can't easily open the card's casing...

	# ./a.out 06:00.0

I haven't tried it yet.
