Backporting
A good guide to backporting is at
https://raphaelhertzog.com/2010/12/15/howto-to-rebuild-debian-packages/
A deb-src line in sources.list for unstable is needed to do:
apt-get source libsane-common/unstable
Then:
apt-get build-deps libsane-common/unstable
should get the dependencies from stable to build libsane-common and libsane.

Configurations
Some notes on kernel configuration options (linux 3.3.8) with some notes about intel splash on a intel chipset notebook. Most of the following is a server setup on AMD though.
CPU Frequency
Set min / max values
create file if not existing
/etc/default/cpufrequtils
define min/max value and governor
GOVERNOR="ondemand" MAX_SPEED="3.6GHz" MIN_SPEED="1.4GHz"

Disable nepomuk in KDE4
1. First you have to stop it:
qdbus org.kde.NepomukServer /nepomukserver quit
2. Then disable nepomuk autostart:
sudo mv /usr/share/autostart/nepomukserver.desktop /usr/share/autostart/nepomukserver.desktop.piece-of-crap
3. Remove nepomuk database:
rm -rf .kde/share/apps/nepomuk
