I'm running fc7 with an fc6 kernel (see my first post, booting raid 1)

lspci reveals my usb2/1394 card:

00:0e.2 USB Controller: VIA Technologies, Inc. USB 2.0 (rev 63)
00:0e.3 FireWire (IEEE 1394): VIA Technologies, Inc. IEEE 1394 Host Controller (rev 46)

But ifconfig does not reveal any ieee 1394 devices.

Reading forums I see that I can modprobe eth1394. It doesn't complain, but neither does it do anything. Not even a hint in dmesg

How can I set up ip networking using firewire? I was unable to find any good reading out there.

I've never tried networking via firewire but check to see if these modules are loading.

No luck

I wish I could find a really good walk-thru on it.

Check the output of the dmesg command to see if there are any messages pertaining to eth1394 like:
eth1394: eth2: IEEE-1394 IPv4 over 1394 Ethernet (fw-host0)

dmesg | grep 1394 yields nothing. According to what I can find, Fedora 7 has a new firewire stack and eth1394 is not implemented yet.

Bummer. There's a number of hours of my life I won't get back again

Kernel 2.6.31-rc1 and higher (such as what comes with Fedora 12) have the firewire-net module, which on loading adds the network interface device firewire0. According to the kernel.org wiki, IPv6 and stability are on the todo list.
