patch for toshiba acpi

[edscott wilson garcia]

I finally got the lcd brightness control and force-fan to work on a
toshiba 2455 on FreeBSD 5.1. If anybody is interested, you can find the
patch at http://linux.imp.mx/toshiba/

In to use it, apply patch and recompile acpi.ko module and copy to
/boot/kernel. Once rebooted, sysctl will see two new variables:
hw.acpi.toshiba.lcd_brightness
hw.acpi.toshiba.force_fan

lcd_brightness has eight values (0-7) and force fan two values (0-1).

Finally I can dim the screen and get rid of this headache...
