Q:

What is a good example of implementing old-school design in a 4e module?

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.

A:

Goodman Games are doing 4e stuff, continuing on from their line of 3e classic style adventures.
Just check out the look and feel of this cover!

At the time of writing there's 17 modules on their 4e section, they were very prolific with their 3e stuff, publishing somewhere around 60 modules.
