Add this to your customization layer:

<xsl:template name="output.html.stylesheets">
  <xsl:variable name="style" select="document($html.stylesheet)"/>
  <xsl:copy-of select="$style"/>
</xsl:template>


The template named 'output.html.stylesheets' handles
the $html.stylesheet parameter when it is set.
In this case, instead of outputting a <link>
element, it copies the stylesheet file into
a variable and outputs the variable's contents.

The catch is that you have to add <style> tags to
your css file:

<style type="text/css">

[css stuff here]
...

</style>

That's because the document() function can only open
XML files, so there must be start and end tags.
But that is ok, since you want the styles to be enclosed
in <style> tags in the HTML anyway.
