This failure looks like an issue with the test program.  The problematic code is this section:

   /* This is one of the modes Xorg creates for panels, so
    * it should work just fine. Notice that Gens that
    * support LPSP are too new for panels with native
    * 1024x768 resolution, so this should force the panel
    * fitter. */
   igt_assert(c->count_modes &&
              c->modes[0].hdisplay > 1024);
   igt_assert(c->count_modes &&
              c->modes[0].vdisplay > 768);
   mode = &std_1024_mode;

There are a few problems here:
 * The platform being tested here has a 13x7 panel which fails the second assert above, even though the panel fitter would still have been used.  We should check hdisplay and vdisplay together to avoid this.
 * If we do come across a true 1024x768 panel on a platform with LPSP we should be skipping this test, not marking it as a failure.  I.e., igt_require() rather than igt_assert().

I think this patch should fix the failure:
