Philip Paeps be38401738 Try to detect a Synaptics touchpad before IntelliMouse. Some touchpads will 
pretend to be IntelliMouse (which have a few more features than generic mice)
causing the IntelliMouse probe to work and the Synaptics code never to be
called.

This should not break "real" IntelliMouse because the Synaptics detection code
is fairly specific.

/*
* 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.
