At this point, it is clear to me that part of the problem is in low-level xorg code - code handling the mapping between the internal X coordinate system and the UniChrome display's coordinate system. It looks, though, like the mapping is correct for the UniChrome display's hardware cursor, when that is used.
But the problem with text (ttyN) displays not working is something else.
