>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.

Nat.
