We have been doing additional work on hald trying to address some
remaining issues, but there is still an issue if you are using a
statically configured sysmouse and hald.

The issue is (with our current work, not sure if marcus has committed
yet) that when the system starts up and moused runs, X has not yet
started and so we mark sysmouse as a valid X input device.  When X
starts, it is enabling it's statically configured devices, then getting
the list of available devices from hald.  Since we already marked it as
a valid device because X wasn't using it at the time, X tries to open
sysmouse again.  For hardware ports, this isn't an issue since the
second open just fails and you keep rolling.  For sysmouse, it happily
allows the port to be opened again.  So, the short story is:

Either set AllowEmptyInput on and let hald add your devices or
statically configure your devices and set "AutoAddDevices" "off"
