I have also run into this problem, after upgrading to Hardy from a fresh installation of Gutsy (64-bit). The mouse is completely unresponsive.
Interesting to know that getting rid of the "InputDevice" sections cures the problem - I will give that a try.
FYI, here is part of my Xorg.0.log file:
(**) Option "Protocol" "10 xserver-xorg/config/inputdevice/mouse/protocol doesn't exist" (EE) Configured Mouse: Unknown protocol "10 xserver-xorg/config/inputdevice/mouse/protocol doesn't exist" (EE) PreInit failed for input device "Configured Mouse" (II) UnloadModule: "mouse" Atom 4, CARD32 4, unsigned long 8
