If you have the info on how to get into diagnostic display I can report what my 
SA3250HD shows when I have myth hooked to it playing LiveTV from one of the 
channels.

Did you ever verify that the firewire modules necessary are all in place? 
There is a listing of them at:
http://www.mythtv.org/wiki/index.php/FireWire

I find it more convenient to use modules than building the code into the 
kernel, primarily because through the use of the hotplug blacklist and listing 
the modules in order in /etc/modules, I can control the order in which eth? is 
mapped to my ethernet devices (one of which is eth1394).

Unless there's an obvious issue with modules, I would probably start a thread 
on the linux1394-user list.
