Hmm.. it may be slower, but I would normally use a recursive function in this 
case.

DTML Method  findRoot

<dtml-if "PARENTS[rootLevel].hasProperty('site_root_folder')">
  <dtml-return PARENTS[rootLevel].absolute_url()">
<dtml-else>
  <dtml-return "findRoot(_.None, _, rootLevel=rootLevel+1)">
</dtml-if>


Use as:

<dtml-var "findRoot(_.None, _, rootLevel=0)">

If you don't mind my asking, why do you need to hunt down this folder?  Is 
there no way Acquisition could be used to simplify your life?

Have a better one,
