+ on "legacy free" Toshiba laptops. These laptops can be recognized by
+ their lack of a BIOS setup menu and APM support.
+
+ On these machines, all system configuration is handled through the
+ ACPI. This driver is required for access to controls not covered
+ by the general ACPI drivers, such as LCD brightness, video output,

+ /proc tree instead of by program interface to /dev. Furthermore, no
+ power management functions are exposed, as those are handled by the
+ general ACPI drivers.
