+.Sh NAME
+.Nm est
+.Nd Enhanced SpeedStep
+.Sh SYNOPSIS
+.Cd "est0 at cpu0"
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for Enhanced SpeedStep introduced in
+Intel's first and second generation of Pentium M processors.
+The following
+.Xr sysctl 8
+variables are available with
+.Nm :
+.Bl -tag -width "machdep.est.frequency.available" -offset indent
+.It Ic machdep.est.frequency.target
+The target frequency of the
+.Tn CPUs .
+.It Ic machdep.est.frequency.current
+The current frequency.
+.It Ic machdep.est.frequency.available
+The frequencies recognized by
+.Nm .
+.El
+.Pp
+Note, however, that these variables are
+not guaranteed to exist in the future versions of
+.Nx .
+.Sh SEE ALSO
+.Xr acpicpu 4
+.Sh CAVEATS
+The
+.Nm
+driver is considered a legacy interface to be used only with old systems.
+It is known to be problematic with new
+.Tn CPUs .
+Furthermore, in the unlikely case where both
+.Nm
+and
+.Xr ichlpcib 4
+or
+.Xr piixpcib 4
+provide support for SpeedStep,
+the PCI-based interfaces should not be accessed due possible race conditions.
