There's always source:
wget ftp://ftp.kde.org/pub/kde/stable/3.4...-3.4.1.tar.bz2
tar xjf kdeartwork-3.4.1.tar.bz2
cd kdeartwork-3.4.1
./configure
make
su
apt-get update && apt-get install checkinstall
checkinstall -D make install

Also the package seems to be on the knoppix dvd. You might want to see if you can repack it.
