- Added some configuration flags as workaround for not-so-compatible

Browse Source 
keyboard/mouse/display switch products (console switches).  Some
  products claim they emulate the PS/2 mouse when the host computer
  talks to the mouse while the mouse is actually routed to another
  host.

	flags 0x200	Do not try to identify the mouse model. All
			mice will be recognized as "generic PS/2".
	      0x400	Do not reset the mouse.  Some switches' response
			to the reset command is too slow and the psm
			will timeout.
	      0x1000	Relax error checking when probing the mouse
			port.

- Added another flag for pad devices.

	flags 0x800	Assume the pad behaves like ALPS GlidePoint
			when the user `taps' the surface of the pad;
			it will be reported as the fourth button.
