Using i915.fastboot=1, I don't see a single flicker from power-on all the way to GNOME desktop. However, just as reported, backlight control doesn't work and is set to maximum. I have additionally tried acpi_backlight=[vendor,native,video] without any success. I can test patches and provide further debug infos, if needed. Please let me know.
