Peter Mikula, from Digital Artefacts, pointed me a simple solution for
getting entityrefs + profiling working. Sharing with the list:

Add this to your customization layer:

  <!--
    entityref + profile fix:
    entity resolver relative to original document
    replace unparsed-entity-uri() calls w/ template call
  -->
  <xsl:param name="da-custom.resolverDocument" select="/"/>
  <xsl:template name="unparsed-entity-uri">
    <xsl:param name="name"/>
    <xsl:for-each select="$da-custom.resolverDocument">
      <xsl:value-of select="unparsed-entity-uri($name)"/>
    </xsl:for-each>
  </xsl:template>

and overwrite all the templates that call unparsed-entity-uri(), for
example 'mediaobject.filename' in common/common.xsl, replacing:

  <xsl:value-of select="unparsed-entity-uri($data/@entityref)"/>

with:

  <xsl:call-template name="unparsed-entity-uri">
    <xsl:with-param name="name" select="$data/@entityref"/>
  </xsl:call-template>

Regards,
Diego
