For my Dell's, I usually added a line into rc.suspend and rc.resume, to 
toggle the acpi video sysctl.  Something like:

sysctl hw.acpi.video.lcd0.active=0

in /etc/rc.suspend, and:

sysctl hw.acpi.video.lcd0.active=1

in /etc/rc.resume.

Now, if your setting is by default =0, then you probably will want to 
add something like this to /etc/sysctl.conf:

hw.acpi.video.lcd0.active=1

So that on boot it gets 'enabled'.
