	# but for select to work, need to select ACPI_VIDEO's dependencies, ick

	select ACPI_VIDEO if ACPI

	help

	  Choose this option if you have a system that has Intel GMA500

	  (Poulsbo) integrated graphics. If M is selected, the module will

	  be called Poulsbo. This driver is a stub driver for Poulsbo that

	  will call poulsbo.ko to enable the acpi backlight control sysfs

	  entry file because there have no poulsbo native driver can support

	  intel opregion.
