That is around the timeframe of the xf86-video-intel update to 2.99.909 from 2.20.19. Currently we have 2.99.910. I don't see any likely commits in the kernel around that timeframe. 2.99.911 has since been released http://lists.freedesktop.org/archives/xorg/2014-March/056491.html When I get a chance I'll test it here and send you a patch to see if that changes anything.
