Yes, all input devices configured statically. 
AutoAddDevices is also turned off. hald is used only 
for removable media detection in KDE. Also I tried to 
use /dev/ums0 instead of /dev/sysmouse - then it works 
fine, but, obviously, USB mouse cannot be 
plugged/unplugged while xorg-server is running. So 
problem appears only with sysmouse.
