Hi, Just to give an up, I'm not an ubuntu user, but have exactly the same problem with an asus N51 core 2 duo and kernels >= 2.6.38. I've been following kernels up to 3.2.7 and the bug persists until now. I was pleased to find the mentioned workaround here: going into standby mode and back does restore normal CPU speed!
Also, turning off ACPI will work with normal CPU speed. The slowdown appears at some rather late stage during bootup, bootup speed with systemd is almost normal.
