So it sounds this is a timing-related problem. I have an old 486DX/33 attached
to the scanner, so maybe it is slow enough most of the time ;-).

Well - they are accepted, but in my case, they are ignored and the whole area
is scanned when it works. This is a "known feature".

Haven't seen that happen. Maybe it does, too, but it is quite infrequent, then.

32K. Unchanged, standard kernel.

At 0. The scanner does its "calibration move" and that's it.
