Hooray!
Your method works, you saved my eyes. I can change brightness level with 
"acpi_call -p "\_SB.ATKD.SPLV" -i $[1-10]. Thanks a lot!

I've made keyboard shortcuts for brightness control. Maybe someone may 
need it -- here I leave the recipe:

1) Granted access to acpi to anybody from wheel group by adding the 
following to /etc/devfs.conf (don't forget to restart devfs service 
after changing the file):

perm	acpi	0660

2) Created two tiny scripts in ~/bin:

brup.sh...

#!/bin/sh
if [ ! -f /tmp/brightlvl ]; then
	echo 1 > /tmp/brightlvl
fi
lvl=`cat /tmp/brightlvl`
if [ $lvl -gt 9 ]; then
	exit 0
fi
lvl=`expr $lvl + 1`
echo $lvl > /tmp/brightlvl
echo $lvl
exit 0

...and brdown.sh

#!/bin/sh

if [ ! -f /tmp/brightlvl ]; then
	echo 10 > /tmp/brightlvl
fi
lvl=`cat /tmp/brightlvl`
if [ $lvl -lt 2 ]; then
	exit 0
fi
lvl=`expr $lvl - 1`
echo $lvl > /tmp/brightlvl
echo $lvl
exit 0

2) Added the following to ~/.fluxbox/keys (if you use another WM/DE then 
you'll have another way to bind hotkeys):

Control Right :Exec acpi_call -p "\_SB.ATKD.SPLV" -i `brup.sh`
Control Left :Exec  acpi_call -p "\_SB.ATKD.SPLV" -i `brdown.sh`

Now I can adjust brightness by pressing Ctrl+Left/Ctrl+Right. Somewhat 
more convenient then typing the command in the terminal.
