Today i didn't managed to set the same url to a translated version from a homepage. Drupal just didn't want to create a english and dutch node with "home" as its pathauto configuration.
I searched the web and couldn't really find it, until i found someone how got the solution on a IRC channel.
You just have to manually add a alias, so both nodes have the same path like "home", you can do that here "admin/build/path/patterns).
And then you can set your homepage to "home" again on the site information page " admin/settings/site-information ".
