You can use crontab(1) to run backlight at reboot. This is what I have:
~> crontab -l
@reboot /usr/bin/backlight 50

A second option could be to load the acpi_video module.
In /etc/sysctl.conf you can define settings as
hw.acpi.video.lcd0.fullpower=70
hw.acpi.video.lcd0.economy=60
For testing you can load the module by kldload und use sysctl to try if
the settings are working with your hardware.

Kind regards,
Christoph
