It's not UniNorth internal firewire ? weird...

Apple love using a new phy for each new model. I just hope it's not yet
another undocumented broadcom part... well if it is (which is probably
the case if it's a gigabit), we might have to wait for the darwin driver
to get updated before beeing able to do gigabit.

Ok, looks like I'll finally have a good excuse to work on this driver :)

Ok. New coders are always welcome ;) There are a lot of things that would
be great on both the M3 (r128) and the new radeon: better support for
external CRT, support for S-video output, better panel detect...
