Thank you for your hint.
Ok, following TeXbook, the kerning with the skewchar definies the placement of
the accents. In the fontinst/mn-oml-*.etx I found
\nextslot{255}
\setslot{skew}
\endsetslot
Looking in enc/mn-t1.enc, /germandbls is the last glyph. So the kerning pairs
X.swash and germandbls define the placements of glyphs. And there are already
kerning pairs like this in kerning/*It*.kern. Fine. (Although they are for
Germandbls so upper case, I guess it's ok.) But running maketfm, I get
warnings like this:
otftotfm: ./enc/mn-It-t1.enckern:169: warning: 'A.swash' has no encoding,
ignoring '{180}'
running eg
otftotfm --tfm-directory=tfm --vf-directory=vf --encoding-directory=dvips --
no-type1 --no-updmap --no-dotlessj --warn-missing -fkern -fliga -flnum -
fpnum --include-alternates '*.swash' -faalt -e 'enc/mn-It-t1.enckern'
'otf/MinionPro-It.otf' 'MinionPro-It-lf-swash-t1'
It seems that the kerning pair and all other swash ones are ignored, because
they are not included in the encoding. So I modified the maketfm script to use
different enckern files for the swash letters where each X.swash kerning pair
is replaced by a X pair (as far as I can see, otftotfm just treats X.swash as
X) and all other uppercase X pairs are removed. And this works! Now, the
accents look nice!
Still, there still a lot of other warnings of this kind, different ones for
different encodings so there might at least one which uses the pairs...
What do you think?

PS: I use the latest version of lcdf-typetools, that still works with the
scripts (2.69). If you had a hint how to get a list of all the changed glyph
names, I could have a look at this. I had a look at the sources of lcdf and I
was not able to retrieve that information.
