I just double checked again and yes with the commit before b2f19d1a1d7b262cf5fbe6033776afcf6d1ab526 - i.e this one:

    drm/i915: Fix new_config and new_enabled for load detect

suspend/resume and modesetting result in a black screen.

Using b2f19d1a1d7b262cf5fbe6033776afcf6d1ab526 there are no blank screen issues in my machine at least.
