Nice to know that, but could you please ellaborate a little please on  
the firmware part, for documentation purposes? I'll try to compile a  
minimal kernel for PowerPC and I will be interested in that (and in  
preparation for the ra*usb* modules too).

I do think that Ben Collins would like to know about this, as I  
imagine that he would like to make things "just work" in a default  
install of future versions of Ubuntu.

I did this with dapper's driver. I had to put, as a pre-up command,  
the following:

# ip link dev ra0 up

(I don't remember the syntax correctly and I'm not using my own  
computer right now to check it, even though it may be a good idea to  
leave this documented, as others may "fall into the same trap").

I will try this as soon as I have some spare time (see below) and  
report back.

Ok.

I think that this shouldn't be needed (under normal circusmstances,  
that is).

Right.

Nice. Did you use the module-assistant package or not?

Here in Brazil, we have a distinction between Computer Science and  
IT. Computer Science being the thing that "makes everything work" and  
IT being the "business part". I teach for both courses and, having  
lots of students of mine, I see the quite different focus that they  
seek.

I am, obviously, quite biased towards Theoretical Computer Science,  
as Graph Theory and its interactions with Abstract Algebra are my  
main interest.


Thanks for your report, Rogério Brito.
