Committed to Intel's X.Org driver git tree (xf86-video-intel) has been four updates in recent days. Ending off July was a commit that added back-light support for the 965GM and also a check to make sure legacy-enabled systems don't reduce the range of user-presented back-light values. Improvements made to the Intel open-source graphics driver earlier today include tiled rendering and fbc fixes, merging the master branch, and limiting solid and copy offsets to 4k when rendering to tiled targets. The latest code and summary of changes are available through the
FreeDesktop.org gitweb.
