this may not work, but at this deb URI there is a 2.4.20-xfs-v412 kernel, alsa headers, and ??

deb http://www.esat.kuleuven.ac.be/~mleeman/debian unstable/

and/or you might want to look at the contents of this suse rpm:
http://rpmfind.net/linux/RPM/sourcef...c6-1.i386.html

you may have to break the rules and extract what you need from the suse rpm, note though that dpkg (apt-get) won't know that the files are present, so you may have to force your way through.

breaking the rules is allowed in linux if it works
