Then it seems Linux miscalculates the MHz if I select Auto in the BIOS. (I need to use acpi pm timer then, otherwise I get lost ticks with tsc.) It is *not* throtteling which results in this, as I can still throttle down via acpi by hand and then the laptop feels very sluggish (same if Linux reports 133 or 500MHz). So I wonder a bit how this comes, but well...
