[Bug 422858] Re: Atom N280 frequency scaling not supported

I've seen this problem on other N280 based systems - specifically, the
kernel is getting the incorrect CPU speed from the BIOS ACPI tables. To
test this hypothesis, try booting with the kernel boot option:

acpi=off

If you get the full 1.66GHz with this option it means that your BIOS is
reporting the wrong speed.
