I recently installed Kde 1.1 on Debian 2.1. I did it this way;
1. Install the qt library version 1.42 -2 from the debian site
2. Download from ftp://ftp.kde.org/pub/kde/Incoming/debian ,
(or a mirror) , the following fpackages and install them using dpkg
(dpkg -i package.deb) in this order:
kdelib2g
kdebase1.1
kdebase-il8n
kdeanim
kdesupport
kdegames
kdegraphics
kdenetwork
kdetoys
kdeutils
kdewallpapers
This desktop is very nice!
