Check out the end of
this thread. It looks like the same code but the smarty code they used to call the manufacturer was different. 7thdesire said this allowed him to see the manufacturer name on the products list.
Try changing (in your template products_t.tpl):
PHP Code:
<div class="brand">{$product.manufacturer}</div>
To this:
PHP Code:
<div class="brand">{$manufacturer.manufacturer}</div>
Edit: I forgot if you are using columns for your products list you want to edit products_t.tpl, if not edit product_list.tpl
