I am Eee PC 1015 PEM, Everything is as described. Except that there is a bug for brighness OSD. At maximum brightness, the OSD isn't at maximum (at about 2/3), however it still take the same 5 notches from minimum to maximum.
On top of that, after adjusting brightness, there will be a drop in brightness when a key is pressed (brightness OSD would appear too). However after adjusting the brightness and another function key is toggled (such as volume), the brightness will drop but will instantly revert (brightness OSD would still briefly appear).
So it's either the volume control or the brightness control.
