Dell's ACPI implementation appears to be implemented on top of this at a
firmware level, so both are consistent. However, in terms of
cleanliness, we should wait for Thomas's patches to be merged so this
driver can disable the backlight support if there's an ACPI backlight
present. The reason I implemented it is that there's no ACPI backlight
support on some currently shipping Dells, never mind the older hardware.
