read brightness from actual_brightness and not from brightness
The get_backlight function read from the wrong sysfs file.
The real backlight value is available from 'actual_brightness', whereas
'brightness' is used for changing/setting the backlight through software.
'brightness' always reads last value writen to it.
Backlight which is hardware controlled, as with many thinkpads (ex T42), does
not update 'brightness'. Thus hald is not returning the right value!
