Re:

Hi Pietro !!!

> I cannot use a stable release of debian due the kernel version, too old for my hardware, can someone suggest me a way in order to investigate better of the nature of my problem ?


Compile your own Kernel !!! This is usual the
steps I do, just to give you idea what to search...
Don't need to be so complex, but I prefer to share
this way

$sudo aptitude install kernel-package  pkg-config
$cd /usr/src/
$git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
linux-git
$sudo adduser YOUR_USER_NAME src
$sudo ln -sf linux-git /usr/src/linux
$cd linux
$sudo make mrproper
$sudo chmod +x scripts/kconfig/streamline_config.pl
$sudo cp /boot/config-VERSION_OF_KERNEL .config
$sudo perl scripts/kconfig/streamline_config.pl > config_strip
$sudo mv config_strip .config
$sudo make oldconfig
$sudo aptitude install libgtk2.0-dev libglade2-dev
$sudo make gconfig
$sudo fakeroot make-kpkg --revision=NAME_YOU_WANT.1.0 kernel_image
kernel_headers

I'm sure something is missing or wrong :D

This is not "branch" is a way to catalog the packages,
you can try;

deb http://ftp.it.debian.org/debian/ wheezy main contrib non-free

Branch may be more something like

the stable "branch"
deb http://ftp.it.debian.org/debian/ stable main contrib non-free

the testing
deb http://ftp.it.debian.org/debian/ testing main contrib non-free

...

;) hope it gives you some light,
