As far as I know, you need to install the usermode 
soundmodem. I don't know if woody includes it, but you can 
download and compile it yourself.

Then you can run the configuration utility, soundmodemconfig 
or something.

Then you need to edit /etc/axports

Then start the soundmodem.

Your soundcard must be supported by oss. Or maybe by alsa 
with oss compatibility enabled.

You need the mkiss kernel module too, in addition to ax25.

I'm not sure, but maybe you need some of the folowing 
packages:

libax25
ax25-tools
ax25-apps

I always install them prior to soundmodem because I need 
them. For example ax25-tools includes kissattach, necesary 
to attach a kiss tnc, and ax25-apps includes listen, that I 
use for monitoring purposes.

I hope you find this usefull. Try to check the ax25-howto 
that can give you more details. If you have any question, 
just ask.
