I've added a repository for the Kanotix release based on Debian wheezy, Codename "Dragonfire", and backported KDE4.8 there:
# Kanotix Dragonfire (with KDE4.8-wheezy-backport by acritox) deb http://kanotix.acritox.com/debian dragonfire main kde-backport deb-src http://kanotix.acritox.com/debian dragonfire main kde-backport
it contains backported amd64 and i386 packages of KDE4.8 (mainly packages from Kubuntu, with some Kubuntu-specific patches removed, some own patches added and some patches adopted from the source-packages of the ZevenOS-Neptune-repository, qt-kde.debian.net and pkg-kde.alioth.debian.org), and some other packages that are patched for Kanotix Dragonfire:
W: GPG error: http://kanotix.acritox.com Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 36A6D2F8ECF82819
then you are missing my public GPG key. You may either install the acritox-archive-keyring package:
