[PATCH] Fix Keymapping for upcoming Dell Laptops

[Jerone Young <jerone.young@canonical.com>]

Currently 0xD8 is being mapped to sleep. Though this is only done by the
Latitude XT* laptops. Many upcoming Laptops from Dell are mapping this
key to "toogle touchpad off" .. giving the OS notification that it has
just turned on the touchpad.

This patch fixes it so that new Dell machines will work correctly as
well as keep the Latitude XT working without issue. As well as adding
toogle touchpad ON keypress as well.
