Sorry about all this.
There's a tight ABI binding between the X server and the
xf86-video-intel driver. That means you can't compile the 2.9 driver
with the latest X server, nor can you compile the latest driver with the
X server that works with the 2.9 driver.
That means it's impossible to hold one of these projects constant while
bisecting the other, (or even just trying a couple of versions of the
other to pinpoint it as the problematic component).
That's unfortunate since bisecting would be extremely useful here.
For this specific instance, one might be able to construct a patch to
the 2.9 driver to make it compile against the latest X server. And then
one could carry that patch along while bisecting. That will be a bit of
In the future, I think the right thing to do is to put the driver back
into the X server repository. That would eliminate this problem
entirely, (for future versions), and bisecting either X server or driver
problems would work just fine.
