NetBSD beast 6.99.7 NetBSD 6.99.7 (LOCKDEBUG) #186: Wed Jul 4 05:47:37 EST 2012 build@beast:/usr/src/sys/arch/i386/compile/obj/LOCKDEBUG i386
>Description:
No Support exists for Panasonic Toughbook computers, although support exists in Linux and FreeBSD.
>How-To-Repeat:
Use NetBSD with a toughbook computer and you'll find most of the hotkeys and tablet buttons (applicable models) don't work.
>Fix:
I found support for it in FreeBSD in 2006 and ported it to NetBSD 3.0.1. I made many changes since then adding and removing support for hw registers and sysctls to suit. Only to finally simplify it for submission.
Also in 2008 I added support for the tablet buttons on the CF18/19 models. Modified it further this year to make it a separate file.
I don't think there is support for tablet buttons in other OSs except Windows.
I'll add the drivers and manual pages to this PR.
Regards,
Nat.

+.Nm panasonic
+.Nd Panasonic TOUGHBOOK laptop features support
+.Sh SYNOPSIS
+.Cd "panasonic* at acpi?"
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for hotkey handling and screen brightness found on
+Panasonic TOUGHBOOK laptop computers.
+.Pp
+The
+.Nm
+driver provides support for modifying the screen brightness via the
+.Xr sysctl 8
+interface.
+.Pp
+The following
+.Xr sysctl 8
+variables are available:
+.Pp
+.Bl -tag -width "hw.panasonic.brightness [R/W]" -compact
+.It Em hw.panasonic.brightness Bq R/W
+Controls current LCD brightness.
+Range [0-100].
+.El
+.Sh SEE ALSO
+.Xr acpi 4 ,
+.Xr acpivga 4 ,
+.Xr pmf 9 ,
+.Xr sysmon_envsys 9 ,
+.Xr toughbook_hbtn 4
+.Sh HISTORY
+The
+.Nm
+device driver appeared in FreeBSD and was extended and ported to
+.Nx 3.0.1 by Nathanial Sloss.
+.Sh AUTHORS
+.An OGAWA Takaya Aq t-ogawa@triaez.kaisei.org
+.An Yoshihiro TAKAHASHI Aq nyan@FreeBSD.org
+.An Nathanial Sloss
+.Sh BUGS
+If the computer is fully supported by
+.Xr acpivga 4 then a different method
+for controlling the screen brightness is used and the above mentioned
+.Xr sysctl 8 variable may not work.
