backlight level is property of kernel driver and can be set/get via
/sys/devices/platform/omapfb/panel/backlight_level file (value 0-127). 
However it is also managed by dsme daemon which resets it regulary 
according to gconf value /system/osso/dsm/display/display_brightness so 
you can set/get it via
# gconftool -g /system/osso/dsm/display/display_brightness
# gconftool -s /system/osso/dsm/display/display_brightness -t int 1
which is what the statusbar applet does. Value 1 means kernel value 3. 
Sadly you cannot go lower without hacking dsme or kernel, see also
