------- Comment #14 from [EMAIL PROTECTED]  2008-07-18 02:02 -------
This patch fixes the issue mostly. First of all
/sys/class/backlight/acpi_video0/actual_brightness now does show actual
brightness. /sys/class/backlight/acpi_video0/brightness shows only real and
actual brightness, i.e. works as intended.

The only issue remaining is that the brightness resets to maximum if initial
brightness is 0 (minimum), after e.g. xset -display :0 dpms force off.
Other values - from 1 to 7 - work as intended, the level is restored properly.
