It will probably only work with USB devices.  kbdmux handles the 
keyboards, and... devd handles the mice, I suppose.

Hmm.  It does not seem to matter which way AutoAddDevices is set, 
plugging in an additional mouse results in both being able to move the 
pointer.  Note that I am using xfce and do not even have HAL installed.
