Система portage

Здравствуйте, уважаемые!

Подскажите как установить старые дрова (версии 96.43.23) от нвидиа?
В x11-drivers/nvidia-drivers есть следующие версии:

nvidia-drivers-173.14.39.ebuild
nvidia-drivers-304.125.ebuild
nvidia-drivers-331.113.ebuild
nvidia-drivers-340.76.ebuild
nvidia-drivers-343.36.ebuild
nvidia-drivers-346.87.ebuild
nvidia-drivers-349.16.ebuild
nvidia-drivers-352.30.ebuild
nvidia-drivers-96.43.23.ebuild

если маскировать все дрова, версии которых выше 96, то
говорит, что nvidia-drivers-352.30 замаскирован и надо размаскировать.

Доброго времени суток.
В Gentoo новичек, не ругайтесь ;)
