mod_bookmarks2: Use max_items='max' on trunk, with fallback check_node_config() throws an error attempting to compare the pep_max_items number with the 'max' string, which allows detecting and support using 'max' where available. Unsure what happens when you upgrade, that seems a problem for a future commit! :)
