[ltp] gnome-screensaver and locking using fn-f2

[Grant Williamson]

Yep, 2 parts

1)
you need to have hotkey-setup running on your machine the thinkpad-keys 
daemon is the important part.

2)
acpi_support package, the acpi_fakey to send a keycode of 152, this will 
lock your screen using gnome-screeesaver.

It's a rather cool way of doing this.
