Thank you for pointing out CONFIG_FUJITSU_LAPTOP, I was not aware of this. 
I have now tried using this module, which results in a directory at
/sys/devices/virtual/backlight/fujitsu-laptop populated with a few files.

taking a look at the files 'max_brightness' and 'actual_brightness' seems to
reveal correct information about maximum and actual brightness respectively.
However, actual_brightness is read only, and I have no idea how I could
influence the brightness using this interface. Neither hal, or the xbacklight
tool seem to be able to use this interface either. This is the list of files
created:

actual_brightness
bl_power
brightness
max_brightness
power
subsystem
uevent
