On my model (Macbook Pro 5,2) and others with simliar graphics setup (two nvidia cards), on kernel 3.10 and some before, backlight support is in the kernel, and the device is at /sys/class/backlight/gmux_backlight.
Pommed v1.40git does not know about this driver. If you want pommed to handle the LCD backlight, it needs to know this path.
This is a matter of a simple 4 liner patch: http://pastebin.com/sCNjtuwD
I can't find where to submit this patch upstream though. Any help?
Also, max_brightness is 16055, so modify your pommed.conf to some reasonable values:
lcd_sysfs {
# The sysfs backlight control is a generic interface provided
# by the Linux kernel for backlight control on most graphic cards.
# The brightness range can differ depending on the hardware.
# initial backlight level [12] (0 - 15, -1 to disable)
init = 14000
# step value (1 - 2)
step = 1000
# backlight level when on battery [6] (1 - 15, 0 to disable)
on_batt = 9000
}

This seems like something that belongs in the Wiki, not the BBS.

I guess I'm looking for help in finding where development happens upstream.
The last commit on master here: git://git.debian.org/git/pommed/pommed.git was in 2011.
I suppose it's not actively developed? Maybe in that case, the package maintainer could include this patch?
