Actually, I wasn't understanding how the preceding axis was working,
nor exactly how your posted code.  So I left out the position
conditional, which was the problem.  This works:

  <xsl:function name="bib:ibid" as="xs:boolean">
    <xsl:param name="citation" as="node()"/>
    <xsl:value-of select="$citation/db:biblioref/@linkend =
$citation/preceding::db:biblioref[1]/@linkend"/>
  </xsl:function>
