Superhai has released a new version of his Powerstep kext. He calls it VoodooPower, with no repercussions yet, but an early release of an ersatz Voodoo 9.6 kernel quickly brought a "Please rename this" from the XNU-Voodoo team. Details at [URL]http://forum.insanelymac.com/index.php?showtopic=143898[/URL] I am using it on a vanilla 10.5.6 install and it works as advertised. Next we need a HyperThread kext :?: and sleep :!:
