You are running an old kernel version (3.2). You might want to install the
latest linux-libre kernel (3.12). It might have the driver you need. You can
find it here: http://jxself.org/linux-libre/
Here are short instructions on how to do it. Please, see the link for
detailed instructions.
deb http://jxself.org/repo/freesh/ freesh main
wget http://jxself.org/repo/freesh/archive-key.asc
sudo apt-key add archive-key.asc
sudo aptitude update
After these steps you need to install the kernel you want (32-bit/64-bit):
sudo apt-get install linux-libre64 OR
sudo apt-get install linux-libre32
Reboot and you have the latest kernel.
