Created attachment 41242 [details] patch for nouveau Kconfig If CONFIG_ACPI is enabled, CONFIG_NOUVEAU selects CONFIG_ACPI_VIDEO. However, CONFIG_ACPI_VIDEO depends on more than just CONFIG_ACPI, and in particular will never be set on ia64. Previously reported with patch at <http://article.gmane.org/gmane.comp.video.dri.devel/52445>
