Patch can be found here, a bit large to inline: http://jsg.id.au/openbsd/xf86-video-intel-2.99.911.diff To apply: cd /usr/xenocara/driver/xf86-video-intel/ patch -p1 < /path/to/xf86-video-intel-2.99.911.diff Then rebuild xenocara and restart Xorg. You should see an entry in /var/log/Xorg.0.log to the effect of [ 17346.336] (II) LoadModule: "intel" [ 17346.336] (II) Loading /usr/X11R6/lib/modules/drivers/intel_drv.so [ 17346.355] (II) Module intel: vendor="X.Org Foundation" [ 17346.355] compiled for 1.15.1, module version = 2.99.911 [ 17346.355] Module class: X.Org Video Driver [ 17346.355] ABI class: X.Org Video Driver, version 15.0 if everything worked. Only lightly tested on gen5/ironlake so far.
