NAME

     vald -- Toshiba Programmable I/O controller


SYNOPSIS

     vald* at acpi?


DESCRIPTION

     Some Toshiba computers have a special I/O controller that handles various
     interface devices.  This special I/O controller is accessed by the
     ``GHCI'' ACPI method.  The vald driver provides some support for it.

     The vald driver handles the following hot-keys:

           Fn+F5  Switch between LCD and External Video output.
           Fn+F6  Decrease LCD brightness.
           Fn+F7  Increase LCD brightness.
           Fn+F8  Switch fan (ON/OFF).

     The vald driver has only been tested on the Libretto L3 and on the
     Portege 3440.
