Actually, it's really easy.

in products.php modify this line:
$search_data["products"]["search_in_subcategories"] = "";

to

$search_data["products"]["search_in_subcategories"] = "Y";

If you want to show all products in all subcategories on the home page you need to modify these lines in home.php:

if (!empty($cat))
include "./products.php";

to

#if (!empty($cat))
include "./products.php";

That's all. I haven't tested this too much so I don't know about unforeseen consequences. I'll refer back if there is a problem.
