I never use Kohana but looking at its doc, if I'm right, this is the closest way to do what you used to do with Kohana.
Route::get('{page}', 'StaticController@index')->where('page', 'page|page2|page3|etc');
PS: take a look at this http://laravel.com/docs/4.2/routing (you probably have already checked the doc but in case..)
