589	  This driver adds support for access to certain system settings
590	  on "legacy free" Toshiba laptops.  These laptops can be recognized by
591	  their lack of a BIOS setup menu and APM support.
592
593	  On these machines, all system configuration is handled through the
594	  ACPI.  This driver is required for access to controls not covered
595	  by the general ACPI drivers, such as LCD brightness, video output,
596	  etc.
597
598	  This driver differs from the non-ACPI Toshiba laptop driver (located
599	  under "Processor type and features") in several aspects.
600	  Configuration is accessed by reading and writing text files in the
601	  /proc tree instead of by program interface to /dev.  Furthermore, no
602	  power management functions are exposed, as those are handled by the
603	  general ACPI drivers.
604
605	  More information about this driver is available at

685
686	  The restricted access region control registers
687	  (rar_registers) are used to pass address and
688	  locking information on restricted access regions
689	  to other drivers that use restricted access regions.
690
691	  The restricted access regions are regions of memory
692	  on the Intel MID Platform that are not accessible to
693	  the x86 processor, but are accessible to dedicated
694	  processors on board peripheral devices.
695
