Possible solution:
Edit this file:
app/design/frontend/{interface}/{theme}/layout/page.xml
Look for this line:
<block type="page/template_links" name="footer_links" as="footer_links" template="page/template/links.phtml"/>It should be inside of an other <block> tag named footer.
Remove it from there and put it inside the <block> named 'header' (same file).
It should look like this (or close to it):
BEFORE:
<block type="page/html_header" name="header" as="header"> <block type="page/template_links" name="top.links" as="topLinks"/> <block type="page/switch" name="store_language" as="store_language" template="page/switch/languages.phtml"/> <block type="core/text_list" name="top.menu" as="topMenu"/> </block>AFTER:
<block type="page/html_header" name="header" as="header"> <block type="page/template_links" name="top.links" as="topLinks"/> <block type="page/switch" name="store_language" as="store_language" template="page/switch/languages.phtml"/> <block type="core/text_list" name="top.menu" as="topMenu"/> <block type="page/template_links" name="footer_links" as="footer_links" template="page/template/links.phtml"/> </block>
Then edit app/design/frontend/{interface}/{theme}/template/page/html/header.phtml
Add this line at the end of the file (or where ever it fits your needs)
<?php echo $this->getChildHtml('footer_links') ?>
Clear the contents of dir var/cache and it should work. You might need to do some css work so the new added links would look nice.
