I tested on a ThinkPad laptop with Intel graphics:

Without patch:

root@somehost:/var/lib/initscripts# cat brightness.intel
512
root@somehost:/var/lib/initscripts# /etc/init.d/brightness stop
root@somehost:/var/lib/initscripts# cat brightness.intel
0

With patch:

root@somehost:/var/lib/initscripts# echo 512 > brightness.intel
root@somehost:/var/lib/initscripts# cat brightness.intel
512

root@somehost:/var/lib/initscripts# /etc/init.d/brightness stop
root@somehost:/var/lib/initscripts# cat brightness.intel
512

I think it should work.

Thanks,
