The forthcoming PHP 5.3.0 release includes late static binding, which might help. Using this feature you could use a static variable inside a static method, and let the late static binding take care of finding the "right" method.

class Foo {
    public static function getDefault() {
        static $default = 'DEFAULT';
        return $default;
    }
    public static function doSomething ($param) {
        $default=static::getDefault(); // here is the late static binding
        $param = ($param === FALSE) ? $default : $param;
        return $param;

    }
}

class Bar extends Foo {
     public static function getDefault() {
        static $default = 'NEW DEFAULT FOR CHILD CLASS';
        return $default;
    }
}
