Have you been to Intel's page? They have some drivers for this chipset... You will have to build it yourself (like the ATi or nVidia drivers), but they are distributed as any other DRI driver is, usually you will only have to run the script to build it. Make sure you have the development tools and the X development libraries and headers installed!
and from the drop-down menu, select Linux*, download the .tar.gz file to a location in your hard drive you can remember, then open a console and follow the instructions Intel provides. However you will have to do that OUTSIDE X, so either take your time, study the instructions, and then do it, or print out the instructions.
