Just a thought: You don't think that the two cpu thing below could be due to intel hyperthreading do you? I've never used a box with a hyperthreading CPU but I'm sure I've read about their CPU's appearing to be two. matt Quoting xsdg (xsdg@freenode.org): > As others have said, you need to get cpufreq working. Personally, I'd suggest installing and using 2.6.0-testN (test9 works well on my laptop). test9 (as well as some others; I forget when it was merged) has cpufreq in the source tree, so all you need to do is enable it and the relevant options.
