Here is what discover1 loads for Firewire:

Module                  Size  Used by    Not tainted
ehci-hcd               25704   0  (unused)
usb-ohci               24136   0  (unused)

and this is what discover2 loads:

Module                  Size  Used by    Not tainted
usb-ohci               24136   0  (unused)

So I manually have to load (by using /etc/modules) eth1394 and
ohci1394. This is on my alpha/2.4.26. I can also check my ibook (ppc)
with discover{1|2} and 2.{4|6} if that makes sense (but I vaguely
remember it to be the same there).

I think always loading is the only possible way. By checking the
proper file in /proc you can of course test if a cable is inserted at
all (i.e. a peer is present). At least in 2.4 this works fine (2.4
Ethernet-Over-Firewire is incompatibel with the 2.6 version,
unfortunately, hence I only tested the 2.4-version).

Hope this helps.

Greetings
