Должны ли иксы жрать столько памяти?

Привет всем.
Имеется eeepc 701 с интеловской видюхой. На нем установлен Arch с последними апдейтами. Дрова для видео - "intel". Для тачпада используется драйвер "synaptics".
Вопрос таков - без иксов система использует примерно 15 Мб памяти, а после запуска иксов, без всяких DE, просто startx - уже около 85. Должно ли так быть? На мой взгляд как-то многовато получается.

Вот конфиг иксов, взял его из арчевской вики.
