An update to my previous post: Today I updated a ton of Xorg components, and rendering performance for the i915 is now back to previous levels. Everything seems to be running as fast as before, including GL.
I updated a *lot* of Xorg components, but my suspicion is that 'xserver-xorg-video-i810' was that one that did it (upgraded from 1:1.0.1.5-2 to 1:1.2.0-3). Others experiencing rendering performance issues with Intel integrated graphics may care to upgrade to the latest versions in unstable.
