Still not completely happy about this part.
I would look at data->output->config.connector for modes, and return 1024 mode if nothing's found.
Saves a whole lot of drm calls.

Use igt_output_override_mode + igt_display calls? With the thread being a fork now, you can use igt_display. :)

data->output->config.connector->connector_id ? Though I don't think we still need it if you use the igt display calls.

igt_output_set_pipe(output, pipe);
Again, shouldn't need crtc_id, but if you did display->pipes[pipe].crtc_id
With those fixed, I don't think you need raw drm calls in this test at all. :)
