- *  Ported to 386bsd Oct 17, 1992
- *  Sandi Donno, Computer Science, University of Cape Town, South Africa
- *  Please send bug reports to sandi@cs.uct.ac.za
- *
- *  Thanks are also due to Rick Macklem, rick@snowhite.cis.uoguelph.ca -
- *  although I was only partially successful in getting the alpha release
- *  of his "driver for the Logitech and ATI Inport Bus mice for use with
- *  386bsd and the X386 port" to work with my Microsoft mouse, I nevertheless
- *  found his code to be an invaluable reference when porting this driver
- *  to 386bsd.
- *
- *  Further modifications for latest 386BSD+patchkit and port to NetBSD,
- *  Andrew Herbert <andrew@werple.apana.org.au> - 8 June 1993
- *
- *  Cloned from the Microsoft Bus Mouse driver, also by Erik Forsberg, by
- *  Andrew Herbert - 12 June 1993
- *
- *  Modified for PS/2 mouse by Charles Hannum <mycroft@ai.mit.edu>
- *  - 13 June 1993
- *
- *  Modified for PS/2 AUX mouse by Shoji Yuen <yuen@nuie.nagoya-u.ac.jp>
- *  - 24 October 1993
- *
- *  Hardware access routines and probe logic rewritten by
- *  Kazutaka Yokota <yokota@zodiac.mech.utsunomiya-u.ac.jp>
- *  - 3, 14, 22 October 1996.
- *  - 12 November 1996. IOCTLs and rearranging `psmread', `psmioctl'...
- *  - 14, 30 November 1996. Uses `kbdio.c'.
- *  - 13 December 1996. Uses queuing version of `kbdio.c'.
- *  - January/February 1997. Tweaked probe logic for 
- *    HiNote UltraII/Latitude/Armada laptops.
- *  - 30 July 1997. Added APM support.
- *  - 5 March 1997. Defined driver configuration flags (PSM_CONFIG_XXX). 
- *    Improved sync check logic.
- *    Vendor specific support routines.
