I can actually see the brightness going up or down. So the notebook is really capable of changing the brightness in 21 levels. When it boots with ACPI enabled there are only 10 levels. The visual brightness difference between value 8 and 9 is noticeable larger than between smaller levels. Levels from 10 to 20 change nothing WRT the brightness - and no error is printed BTW. So my conclusion is: The maximum brightness "comes to early". The upper 10 brightness levels are skipped.
