I regularly test Intel graphics on a Core 2/i965 laptop but your chipset is
even older than that.

The drm/i915 driver wasn't updated in one step from 4.2 to 4.4. You could try
to use git to bisect which particular set of changes broke it. We then would
have more chances to find out what is going wrong.

Another thing you could try is to update to DragonFly master where the driver
has once again be updated. With luck you could have better results.
