It turned out my report of success was wrong. However I think I cornered the problem. The following lines are two snippets of xev output: KeymapNotify event, serial 28, synthetic NO, window 0x0, keys: 69 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 ButtonPress event, serial 28, synthetic NO, window 0xe00001, root 0x145, subw 0x0, time 2952962341, (21,177), root:(1649,206), state 0x0, button 1, same_screen YES Both events are the result of pressing the left mouse button. Sometimes the first, sometimes the second message appears. So it seems that Xorg has trouble with /dev/sysmouse. If I omit moused and configure X to take the mouse from /dev/ums0, everything seems to be fine. The same, if I opperate without a mouse.
