Debian will, by policy, install KDE4 into prefix /usr, like anything else.
However, since this makes certain conflicts unavoidable, the only parts of 
both KDE versions which are installable in parallel are basically the kdelibs 
and some part of kdebase.

The goal is to allow running KDE3 applications in a KDE4 session or to run 
KDE4 applications in a KDE3 session, e.g. just using a few of the new bits, 
probably Okular, games and so on.

KDE4 applications will of course be able to read config and data from their 
KDE3 versions, but it isn't guaranteed that the KDE3 version can then still 
use it, e.g. an upgrade script might have changed it.

If you are still on Debian/SID you could first try to change back to those KDE 
packages (working fine here), thus starting with the same situation as 
several other people as well.
