I've done some poking around and haven't found anything. It looks like the RPGA "Village of Hommlet" drew on its heritage a bit, but I'm pretty sure I won't be able to get my hands on that. I also know (vaguely) the OGL limits who can put out modules, but I thought I'd see if anyone has seen anything.
EDIT: Per the request in the comment, I'm clarifying that I'm not looking something that meets a specific set of old-school criteria, just anything that people feel is in line with some of the design philosophy trends of earlier games.
