Indeed, the kernel support seems broken. I can change the values
in /sys/class/backlight/acpi_video0/brightness but they have no impact
on the brightness.

Charles, setting "xrandr --output LVDS --set BACKLIGHT_CONTROL native"
should make at least xbacklight work, but for HAL which relies on the
ACPI interface, this is up to the kernel.

Thanks to all for the help,
