Also note: In the log of comment #2 it shows that the DRI driver that supports i865 hardware is "i915". And we're already aware that Mir doesn't yet fully support the i915 Mesa driver. But it should do in the near future --> bug 1275398
Once bug 1275398 is fixed we should only need to adjust Mir's EGL config logic to fix this bug. But that's very difficult without any hardware to test on.
