586	  their lack of a BIOS setup menu and APM support.
587
588	  On these machines, all system configuration is handled through the
589	  ACPI.  This driver is required for access to controls not covered

591	  etc.
592
593	  This driver differs from the non-ACPI Toshiba laptop driver (located
594	  under "Processor type and features") in several aspects.
595	  Configuration is accessed by reading and writing text files in the
596	  /proc tree instead of by program interface to /dev.  Furthermore, no
597	  power management functions are exposed, as those are handled by the
