Maybe not officially, but I have a couple of these and I was extremely
annoyed at how hard it was to get it all working properly. So I've been
poking at it a little bit.

First, we ideally need to ditch the need for the userspace 'modem_run'
tool which loads the firmware and monitors the line status, and make the
kernel driver complete. For this we need to work out why the patches at
http://marc.theaimsgroup.com/?l=linux-usb-devel&m=109632100700275 and at
http://marc.theaimsgroup.com/?l=linux-usb-devel&m=109635896807369 both
fail to actually load the firmware, despite being an identical copy of
what gets done in userspace. It would help if someone with more usb-fu
than myself (Pete) could take a look -- maybe I'm missing something
totally obvious in my initialisation which gets done automatically for
the userspace tool via hotplug+usbdevfs. I'd never actually looked hard
at the contents of drivers/usb before yesterday.

Then we need to clean up the pppoatm plugin for pppd so that it's
actually acceptable to the pppd maintainer and it gets merged into pppd
properly. I asked him about it in July and he muttered something about
the way it negates options?

After that we can ship the new kernel driver, linux-atm and pppd with
pppoatm plugin, and then move on to fixing up the initscripts and
system-config-network accordingly. While we're at it, the pppoe support
wants switching to use the pppd plugin instead of rp-pppoe too.
