I think I know why. Build xorg-server without HAL support option and
the attached patch. With HAL support (default) and hald running,
xorg-server auto-detects individual ports with input.mouse capability
even without configuration lines in xorg.conf. If moused is enabled
and USB mouse is used, /dev/ums0 is directly used because there is a
problem in MD code (see attached patch). If moused is enabled and
PS/2 mouse is used, you end up with two input devices
via /dev/sysmouse and /dev/psm0. I couldn't find a cleaner way to
fix this problem, though. :-(
