I'm using this for pppoa now with the firmware from http://www.speedtouchdsl.com/driver_upgrade_lx_3.0.1.2.htm, (ie SpeedTouch330_firmware_3012.zip) and software from http://speedtouch.sourceforge.net/index.php?/download.en.html (which I compiled myself).
The speedtouch-setup script was very easy to use.
I had to recompile my kernel to include modules for ppp, atm and hdlc line discipline (I already had the hotplug and usb stuff active).
Otherwise it was easy! Works perfectly so far. One thing is that I have to run "speedtouch-start" as root and I don't know enough to be sure this isn't a security risk.
