Patch to add the control

Currently the xbacklight utility fails to control the backlight on Sony VAIO Notebooks with Intel graphics.

The sony_laptop linux kernel module (since v2.6.23) supports backlight control
via the sysfs interface:
/sys/class/backlight/sony

The attached patch will enable xf86-video-intel to use this backlight control method for Sony VAIO Laptops with Intel integrated video.
