Say Y here if you have a PS/2 mouse connected to your system. This
includes the standard 2 or 3-button PS/2 mouse, as well as PS/2
mice with wheels and extra buttons, Microsoft, Logitech or Genius
compatible.

Synaptics, ALPS or Elantech TouchPad users might be interested
in a specialized Xorg/XFree86 driver at:
<http://w1.894.telia.com/~u89404340/touchpad/index.html>
and a new version of GPM at:
<http://www.geocities.com/dt_or/gpm/gpm.html>
<http://xorg.freedesktop.org/archive/individual/driver/>
to take advantage of the advanced features of the touchpad.

If unsure, say Y.

To compile this driver as a module, choose M here: the
module will be called psmouse.
