Certainly someone should jump to your side who has the hardware and mastered it successfully :)
I'm using the modem and have been trying to get it working for ages. Give me a weekend and I'll see what I can do with the new information!
Ever get the feeling of : Linux + complications = death?
Well not quite that bad - after all I have it working at the moment. It just won't start up cleanly. I think that the problem is a basic kernel problem that has stopped the kernel mode driver working in a few versions. Hence lots of people have hacked it to get it going again (probably without internet access for help and coordination). Having two drivers floating around can't help either!!
It needs a driver expert to sort out the kernel mode driver and someone to explain the right way to get the hotplug stuff working cleanly so that it loads the firmware when required, before the PPPoE or PPPoA stuff gets triggered. Once its up and running, it seems to go fine.
