Thanks. That's very useful. Raises lots more questions though :)
I wonder how you found out about this. Tral and error? Is this documented
somewhere? What logic decides what points to what? How sure can we be that
this will always be the case? What if someone uses an external USB wireless
card, for instance? And what about BlueTooth? And why is there only one
FireWire interface listed while this PowerBook has 2 (FW 400 and 800)? Can
the answers to these questions be retrieved scriptually? :)
