You probably still have the "mouse" and "kbd" drivers in your xorg.conf
something like this::

Section "InputDevice"
         Identifier  "Keyboard0"
         Driver      "kbd"

Section "InputDevice"
         Identifier  "Mouse0"
         Driver      "mouse"

You should delete those InputDevice sections completely because newer
Xorg servers don't need them.  The "evdev" input driver finds the mouse
and keyboard without any configuration.

You can remove the "mouse" and "kbd" drivers from your machine, too,
as they've been replaced by "evdev".
