It didn't for me either :)

It was a concern for me as since upgrading to Jaunty, frequency
scaling stopped working and my E8500 is stuck at its maximum speed
(3.16GHz) while it was running at 2GHz previously

When you lower the CPU frequency, the external data bus isn't slowed
down (unlike AMD for example). So the overall system continues to
operate at the same speed.

And measuring with my kill-a-watt meter confirmed it, it made no
difference between running my CPU at 2 and 3.16GHz
