[There is no current general resolution to using directory-reserved paths, but it's surely possible with custom Apache rewrite rules-- apparently everyone concludes (as i am right now) that it's not worth the effort!]

Partial Resolution

To .htaccess, add:

    # Allow the modules path to be used by Drupal for the modules chapter.
    RewriteCond %{REQUEST_URI} ^/modules/?$
    RewriteRule ^ index.php [L]

Update: Issue posted. http://drupal.org/node/1028214

The goal is to use the book-variable.tpl.php (exactly like the book-variable.tpl.php is used, including how it gets overridden by themes) but without its preprocess function. Here's one fallback approach that should work, but doesn't, due to seeming weirdness in Drupal:

Now a module! http://drupal.org/project/showaliases

drupal show all paths
drupal show all paths for a node
show alias
aliases
paths
drupal module list aliases

Show path aliases to nodes in other languages
