Make backlight adjustment work in Ubuntu on the Panasonic CF-R7

I was struggeling with the backlight quite for a while now. But finally I found something which finally works.

First you need git core installed

sudo aptitude install git-core

Next you checkout the module

git clone git://git.myrix.net/pana_acpi

The next step is compiling and loading the module

cd ./pana_acpi
make
make install
modprobe panasonic_acpi

At this point you can already check if the brightness buttons are working.
Next copy ./pana_acpi/acpi/* to /etc/acpi
and restart the acpid daemon.

/etc/init.d/acpid restart

This module should work on all the 7-Series from Panasonic. I only tried it out with my CF-R7.
