For Intel, the Open Source drivers that come with Ubuntu are always up to date. There is no need to update them (Very different than ATI or Nvidia for example). Ubuntu always comes with the latest Intel driver when it comes out and it also updates the Intel drivers with the most updated Open Source version available.
Intel is one of the many companies that work a lot in the Open Source world and delivers very good, stable drivers. They also do many updates every year for old and new video cards. Just in case you have any doubts, Ubuntu updates it's Intel video drivers to any still supported version of Ubuntu, that means that your 12.04 will have the latest open source Intel drivers.
