I tried
$ lshal | grep system.hardware.vendor
 I got system.hardware.vendor = 'Sony Corporation'

$ lshal | grep system.hardware.product
 I got system.hardware.product = 'VGN-SR29VN_S'

Then in the file /usr/share/hal/fdi/information/10freedesktop/10-laptop-panel-hardware.fdi
I added the following

      <match key="/org/freedesktop/Hal/devices/computer:system.hardware.vendor" string="Sony Corporation">
        <match key="/org/freedesktop/Hal/devices/computer:system.hardware.product" string="VGN-SR29VN_S">
          <merge key="laptop_panel.brightness_in_hardware" type="bool">false</merge>
        </match>

After reboot, I still can't change the brightness. Is it because my laptop does not support the brightness in hardware, and the problem comes from somewhere else ?
