I've discovered a slight difference with i915.alse_backlight=1:
the actions over the intel_backlight interface (script associated with key combination [ echo NUM >intel_backlight ]) can reestablish a correct screen brightness while without that kernel parameters, those same actions, seem to be ignored!
