Here's what I came up with when someone asked about this back on 7/7:

#untested back-of-the-envelope coding!
#Uses the gtk standard of returning False on match.
def search_func(model, col, key, iter, user_data):
    value = model.get_value(iter, col)
    return value!=key

def search(model, col, key, iter, search_func, user_data):
    if search_func(model, col, key, iter, user_data):
        for i in range(model.iter_n_children()):
             child = model.iter_nth_child(i)
             search(model, col, key, child, search_func, user_data)
    else:
        yield iter

it = model.get_iter_first()
mysearch = search(model, 0, 'foobar', it, search_func)
matches = list(mysearch)
