Hmm... I'm stumped.  The patch shouldn't cause any visible difference
to the userland.  I went over it a couple more times and still can't
see how this would make any difference.  Can you please do the
followings?

* Repeat the test on v3.14 with only the patch reverted.  If it makes
  the problem go away reliably,

* strace X startup on v3.14 and v3.14 sans the offending patch.

Thanks!
