For other reasons I am bound to use kernel 3.4.105, without any trouble,
including xf86-video-intel versions up to 2.99.916.

Upgrading xf86-video-intel to 2.99.917 breaks this setup; however, it works in
combination with latest linux-3.19-rc1+ (which I'm currently testing for fixing
the reason I'm stuck with 3.4.x).

All using X.Org X Server 1.16.3; the regression is reproducable:
