I agree you may have more of a problem than just a cracked cieling. Well
ignoring the obvoius stabalize the foundation and frame first comment I
noticed you describe it as 1x2 lumber supporting the cieling. I have never
seen that. In the US common construction practice is 2x6 joists spaced at
16" to 24" depending on roof load. (noticed you use inches and mm in the
same paragraph)
Since you will need to do extensive plaster repair anyway, just use a nail
or small drill to poke holes in a row to locate the wood definately.
