This patch resolves the issue, but to be precise we should also set
    /org/freedesktop/Hal/devices/dell_lcd_panel: laptop_panel.brightness_in_hardware = true
in hal-info(?). To do it manually:
    sudo hal-set-property --udi '/org/freedesktop/Hal/devices/dell_lcd_panel' --key laptop_panel.brightness_in_hardware --bool true

However SetBrightness does not seem to work on this model anyway, so it does nothing. This means dim on idle/dim on battery does not work. GetBrightness does work.

Can one of the hal maintainers have a look at this patch?
