If you are using Ubuntu 12.04, you can add the pali PPA for the latest open source graphics drivers and linux-firmware.
sudo add-apt-repository -y ppa:pali/graphics-drivers; sudo apt-get update; sudo apt-get dist-upgrade -y
Otherwise if you just want linux-firmware:
cd /tmp; wget http://launchpadlibrarian.net/161429534/linux-firmware_1.118_all.deb; sudo dpkg -i linux*.deb
Or you can upgrade to Ubuntu 13.10/14.04
