I think what you need is:
<?php
$post_id = $post->ID; //or somehow get the current post ID.
$ancestors = get_post_ancestors($post_id)
//$ancestors is an array of post IDs starting with the current post going up the root
//'Pop' the root ancestor out or returns the current ID if the post has no ancestors.
$root_id = (!empty($ancestors) ? array_pop($ancestors): $post_id);
For more info check: http://codex.wordpress.org/Function_Reference/get_post_ancestors

Thank you very much! I tried alexleonard's solution first, and it worked, but then i ran into the issue when im at "subpages" i still want to display the "grandparents" menu. It works great now with the edit :) Thank You! Feb 25, 2012 at 9:46

Please accept this answer (using the checkmark beneath the question up/down voting buttons), if it resolves your problem. May 22, 2012 at 15:45
I think a better solution than @alexleonard 's is to use the parent_id parameter of the post object.
$parent = ( $post_obj->parent_id != 0 ) ? $post_obj->parent_id : false;
Haven't tested that, so make sure you check for spelling mistakes and such.

alexleonard's method will get the top-level parent (parent of parent of parent, etc.), which seems to be what Anton wants. Feb 24, 2012 at 12:35

@AdamBackstrom I'm not sure that that's the case...I think the question could be read either way (having reread it, I can see your point though)– mor7iferFeb 24, 2012 at 13:19
