После обновления мира xorg-server перестал работать

Обновился с emerge -NuD world, после чего х-сервер отказывается стартовать. Пробовал откатить и сам сервер и библиотеки с дровами с 1.9 на 1.7 - не помогает. Создает новый конфиг без проблем, но и по нему не запускается, никаких внятных ошибок не говорит. Вот последний кусок Xorg.0.log:
