Installing SpeedTouch 330 on 3.3

HI all
I have been trying to install a SpeedTouch 330 USB modem on my sisters portable with a HD install of KNOPPIX 3.3. After a lot of trying I have found the Speedbundle-1.0 'package'.
It seems to be a very smart and helpful way to do it, but it stumbles when it tries to build the driver. I suspect it is because it needs the kernel source, which I guess is not on the CD.
Has anyone had succes with the SpeedTouch USB modem with KNOPPIX?

Greetings and thanks
Morten
