on Dell 1300B I use module acpi_video
add to loader.conf acpi_video_load="yes"

and configure devd.conf to run script on lid change status: exist in
it's examples.

notify 10 {
        match "system"          "ACPI";
        match "subsystem"       "Lid";
        action                  "/sbin/lidctl $notify";
};


# cat /sbin/lidctl
#!/bin/sh
hive=hw.acpi.video.lcd0.active
sysctl=/sbin/sysctl

case "$1" in 
        "1" | "0x01") 
                ${sysctl} ${hive}=1 >/dev/null
        ;;
        "0" | "0x00") 
                ${sysctl} ${hive}=0 >/dev/null
        ;;
esac
