[I assume you're using DocBook here, as in your first question.]
IMHO, at least part of the problem is that the FO stylesheets don't
reduce the font-size of the footnote mark by enough (90% relative to
surrounding text) -- even if the baseline shift you describe didn't
occur, I think the mark is too large.  (I don't know off-hand what
relative size (La)TeX, for example, uses, but I'm sure it's smaller.)
I've been experimenting with smaller marks: 60% in Times Roman causes
no baseline shift (that I can detect), though maybe the mark looks a
little too small at this size.  YMMV with other fonts.  Anyway, the
customisation involves a single template:

  <xsl:template name="format.footnote.mark">
    <xsl:param name="mark" select="'?'"/>
    <fo:inline baseline-shift="super" font-size="60%">
      <xsl:copy-of select="$mark"/>
    </fo:inline>
  </xsl:template>

See if that helps.
