This is a symptom of openning /dev/sysmouse multiple times.  You have

Option "AllowEmptyInput" "off"

and there is a mouse section pointing to /dev/sysmouse in xorg.conf, 
i.e., /dev/sysmouse is configured via your static configuration AND 
via hald.

- If you don't have to keep "AllowEmptyInput", then just remove the 
option.  The mouse section will be ignored and hald will do the right 
thing now.

- If you really have to keep "AllowEmptyInput" for some reason, then 
you should remove mouse section from xorg.conf OR you may add 
"AutoAddDevices" "off" in the server layout section.

I hope it helps.
