Log Message:
Move vald(4) to sys/dev/acpi. This is MI and should work also on amd64.
ok jmcneill@
XXX: This is broken: it calls methods with absolute pathnames (almost
guaranteed not to be portable across models), it accesses methods
that are in the domain of other drivers, it walks the namespace on
its own, it contains plenty of magic constants, it does not
integrate with existing KPIs, etc. Summa summarum: this should be
rewritten as a more generic toshiba_acpi(4).

+.Nd Toshiba Programmable I/O controller
+.Sh SYNOPSIS
+.Cd "vald* at acpi?"
+.Sh DESCRIPTION
+Some Toshiba computers have a special I/O controller that handles various
+interface devices.
+This special I/O controller is accessed by the
+.Dq GHCI
+ACPI method.
+The
+.Nm
+driver provides some support for it.
+.Pp
+The
+.Nm
+driver handles the following hot-keys:
+.Pp
+.Bl -tag -compact -offset indent -width "Fn+F5"
+.It Fn+F5
+Switch between LCD and External Video output.
+.It Fn+F6
+Decrease LCD brightness.
+.It Fn+F7
+Increase LCD brightness.
+.It Fn+F8
+Switch fan (ON/OFF).
+.El
+.Pp
+The
+.Nm
+driver has only been tested on the Libretto L3 and on the Portege 3440.
+.Sh SEE ALSO
+.Xr acpi 4
+.Sh HISTORY
+The
+.Nm
+driver appeared in
+.Nx 1.6 .
+.Sh BUGS
+.Nm
+may have problems with X11 when switching between LCD
+and External Video output.
