Returning to your original question: I came across http://talk.maemo.org/showpost.php?p...&postcount=183
This modified version will give you 2, 12 or 25 brightness (on a scale of 0-225) on level 1 with the brightness app. At high brightness it should go to 0, but I could not reproduce that (maybe te lightsource was not strong enough). Other levels have fixed values (no more light sensor corrections, as not everyone liked it).
I have been playing with it, and created a version which will have a fixed brightness value of 2 on level 1. That is almost without backlight, but I have not been able to get it to value 0.
Perhaps you are interested in trying yourself, installation instructions in the referring post.

Thanks a lot, although, I was aware of this one - honestly, never like the "no light sensor" things, as IMO, N900's light sensor and its Maemo implementation is working great, adjusting screen "just-as-required" with respect to user set brightness level (had contact with Galaxy Tab 3 7'' recently, and light sensor implementation in Android is *terrible* - usable only in dark room, which kinda defeats the purpose 
)
I think what I need is to modify SBA code to include a "sticky" button, that will apply your command from previous post and ensure it gets executed on screen lock/unlock. Will work on it "someday".
/Estel
// Edit
And to actually disable light meter *only* for 0-brightness check, as change in ambient light also triggers returning brightness value to "regular" setting, overwriting our echo'ed 0 :| Which mean, that stuff from that linked post may actually get handy, although it would be irritating to use modified library just for this purpose. Need more research if it's possible to temporary disable light meter without that?
BTW, en we're at it, any idea, what the "enable energy saving" from "display settings" (in control panel) is for? I don't see any difference, no matter if it's enabled or not.

It lowers backlight brightness if there's lots of dark colours on screen. It has different modes, accessible through /sys only, for movie, photo, etc
Probably does nothing on highest and lowest backlight setting.

What about opening HW keyboard and type in terminal:
Sorry for noise
Code:
echo 0 > /sys/devices/platform/omap2_mcspi.1/spi1.0/disable_ts

OK, here is my working solution now, based on Ade's tip and searching in various places:
/usr/sbin/disable-backlight.sh
/usr/sbin/enable-backlight.sh
Current limitation - it require setting screen to "never blank" (for example, via simple brightness applet), or, after given timeout, backlight will come back again (faded).
Also, side effect of starting mce is that device asks for lock code. No problem if someone doesn't use one (unwise), or doesn't use ambient light sensor (then it doesn't require restarting mce). Probably, won't be a problem with MCE replacement, after approriate feature request.
Now, I need to find how to disable screen blanking timeout from terminal (just like checkbox in simple brightness applet does).
Cheers,
/Estel

Code:
mkdir /home/user/.disable-backlight
Code:
#!/bin/sh #Saving user's current choice of display blanking mode gconftool -g /system/osso/dsm/display/inhibit_blank_mode > /home/user/.disable-backlight/dim #Let's disable screen blanking, so it won't get "dimmed", resulting in backlight getting enabled again... #Disabling dimming and keeping blanking would be better, but settings allow only the opposite situation :( gconftool -s --type int /system/osso/dsm/display/inhibit_blank_mode 3 #Disabling ambient light sensor's influence on screen brightness, for a while... sed -ie 's/brightness-als/brightness-simple/' /etc/mce/mce.ini stop mce || exit 1 sleep 1 start mce || exit 1 sleep 2 #Saving current backlight value, and disable backlight completely cat /sys/class/backlight/acx565akm/brightness > /home/user/.disable-backlight/brightness echo 0 > /sys/class/backlight/acx565akm/brightness #bye bye exit 0
Code:
#!/bin/sh # Setting user's choice for dimming DIM=$(cat /home/user/.disable-backlight/dim) gconftool -s --type int /system/osso/dsm/display/inhibit_blank_mode $DIM #Enabling ambient light sensor's influence on screen brightness, again... sed -ie 's/brightness-simple/brightness-als/' /etc/mce/mce.ini stop mce sleep 1 start mce sleep 2 #...and enabling initial backlight BCL=$(cat /home/user/.disable-backlight/brightness) echo $BCL > /sys/class/backlight/acx565akm/brightness #bye bye exit 0

Thanks, the 2nd (undocumented) solution works great for this! I've updated scripts in last post, to show their new iteration.
Now, I only need to determine how to prevent opening/closing keyboard (or locking/unlocking device) from resetting backlight levels... Or, make it a feature request in mce replacement (why the hell opening/closing keyboard without dimming/locking screen even touches brightness in the first place?!).

Also, the scripts need to be run as root.
One probably unintended consequence is that screen rotation doesn't work anymore.
