Well, it doesn't look like (it seems to me that all the init stuff is done
in net/core/netpoll.c::netpoll_setup()).
During my tests, I used modules for sungem and netconsole, and I'm actually quite sure that the chip was up, as I had an ssh session to the remote host... I also tried to issue some stuff via 'netcat -u 6666' and it worked. It only looks like the netconsole/netpoll isn't sending anything.

Shouldn't be a problem neither, as everything is already up when I do my tests.

I'll try find more about all this.
