As in my partman log there where millions of OUT - lines, I focussed to the
lines that look quit similar to fdisk output, like:

... and these lines confused me, as wiki said, that biggest value from chs is
1023 - and for me the values in round brakets looked like chs values.
As I'm no hero in juggling hex numbers by mind, I wrote a little helper, that
dumped the mbr infos.
Trying then your advice with "parted -I" I got values similar to the output of
my dumper, but not matching the values from partman, so I came to the same
conclusion as you - where I had to look at the man pages of parted to find a
smaller unit than sectors.
So I added little math to my dumping tool and finally the values matched.
From manual I already read about the rescue option and as you recommended the
same, I gave it a try.
... but I got an error, about missing or wrong label. - Huh?
Did not used any label yet.
So I added writing capabilities to my dumper and created a mbr, where I
thought, should match. Then I wrote it to the drives mbr using dd and rebooted
...
Voila - drive is recognized and all works well.
Thank you very much for your patience and assistance.
kind regards
Gero
P.S. on writing my dumper and checking all drives against partman log, may be
I found a little bug from partman (don't know, whether it has any relevance):
According to wiki, head and cylinder are 0-based, whereas sector is 1-
based. So I think, a value of (0, 1, 0) as above is invalid and should not
occure. I happen to notice 0-based sectors on every drive.
