	Putting it in /boot/loader.conf doesn't work since at some port
during the system bootup, it will set the hw.acpi.lid_switch_state: S1
back to S1.  My /boot/loader.conf is as follows:

hw.ata.wc="1"
snd_ich_load="YES"
acpi_dsdt_load="YES"
acpi_dsdt_name="/boot/acpi_dsdt.aml
hw.acpi.lid_switch_state=NONE

	Doing /sbin/sysctl -w hw.acpi.lid_switch_state=NONE in
/etc/rc.local does work which was the way I had it before but without the
ACPI_DSDT patch, all it does when I close the lid is suspend the machine
without the LCD going off and the LCD isn't alive until I reboot the
machine.  Same thing happens with hw.acpi.lid_switch_state=S1 even with
the DSDT patch is that when the system resumes, the LCD is not live
either.  With the DSDT path and hw.acpi.lid_switch_state=NONE, the LCD
turns off without suspending but when you open the lid, the LCD doesn't
turn on until you hit Fn-F10.  This is with the A10 BIOS on the Dell
Inspiron 8200.
