VIA Fire II Firewire Card

[dieterbsd at engineer.com]

Do you have any other PCMCIA cards?  If so do they work with FreeBSD?

Have you tried a verbose boot?  It gives slightly more data:

fwohci0: <VIA Fire II (VT6306)> port 0xa800-0xa87f mem 
0xfdffe000-0xfdffe7ff irq 18 at device 6.0 on pci1
fwohci0: Reserved 0x800 bytes for rid 0x10 type 3 at 0xfdffe000
ioapic0: routing intpin 18 (PCI IRQ 18) to lapic 0 vector 53
fwohci0: [MPSAFE]
fwohci0: [ITHREAD]
fwohci0: OHCI version 1.10 (ROM=1)
fwohci0: No. of Isochronous channels is 4.

Looking through the code:

/usr/src/sys/dev/firewire/fwohci.c: fwohci_init(struct fwohci_softc 
*sc, device_t dev)
I suspect that sc contains bogus data, in particular:
        bus_space_tag_t bst;
        bus_space_handle_t bsh;

It might be useful to add a printf in fwohci_init() to display the 
values for bst and bsh.
