XEN can't allow this and the calls needs to be done via a hypercall into xen. I only found a hacky patch in http://article.gmane.org/gmane.comp.emulators.xen.devel/22282, which converts one of the speedstep modules to use xen. Does someone know if there is another solution raising? Bastian -- "Beauty is transitory." "Beauty survives." -- Spock and Kirk, "That Which Survives", stardate unknown
