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.
