two scripts for X220 users

Hi,

I would like to share two scripts I found useful running FreeBSD on an X220 with Intel KMS.

Script to start X:

http://www.alogreentechnologies.com/freebsd/XonX220

starts X after it loaded i915kms and acpi_call. 

The machine must have /usr/ports/sysutils/acpi_call installed.

This script was inspired by http://wiki.freebsd.org/Intel_GPU

Script to set LCD brightness:

http://www.alogreentechnologies.com/freebsd/setbrightness

sets the brightness of the LCD.

As I only have one X220 with an Intel CPU, the scripts have not been tested on any other machine.

Feel free to use them and comment on them.

Erich
