AFAIK there's no way to do this without creating a custom view. The concept is a little flawed anyway, because a user would expect such a row to show the total for only the visible objects, rather than all the objects in the queryset. Thus, any pagination would result in confusion.

As an aside, you can add extra columns to an admin list view by doing something like the following:

class ItemAdmin(admin.ModelAdmin):
    model = Item

    list_display = ('field1', 'field2', 'extra_field')

    def extra_field(self, obj):
        return u'%s' % do_something_with(obj)
