I have this setup..

/etc/rc.lid <- set mode 751
--
STAT=`sysctl hw.acpi.video.lcd0.active |awk '{print $2}'`

sync && sync && sync

if [ $STAT = 1 ]; then
        logger -t Lid Close at `date +'%Y%m%d %H:%M:%S'`
        sysctl hw.acpi.video.lcd0.active=0
        sysctl hw.acpi.cpu.throttle_state=1
        echo A >/dev/speaker
else
        logger -t Lid Open at `date +'%Y%m%d %H:%M:%S'`
        sysctl hw.acpi.cpu.throttle_state=8
        sysctl hw.acpi.video.lcd0.active=1
        echo C >/dev/speaker
fi
--



/etc/sysctl.conf
--
...
..
hw.acpi.video.lcd0.active=1
hw.acpi.lid_switch_state=NONE
--

/etc/devd.conf
--
...
..
notify 10 {
        match "system"		"ACPI";
        match "subsystem"	"Lid";
        action			"/etc/rc.lid";
};
--


Notes::

Remember to set en the /etc/rc.conf (devd_enable="YES").


I think that the acpi_vid.ko haves i small error the hw.acpi.video.*.active sude start =1 not =0
this is way a put =1 in the sysctl.conf, because i like to start with my TFT ON xD

My XF86Config-4 file http://www.x123.info/docs/i8500/XF86Config-4

Any comments plz email me..

Thax one more time for the creation of acpi_vid.ko xDD
