I solved the problem by removing the NullCPUPowerManagement.kext and the SleepEnabler.kext I have Cameleon generate the P-states and sleep and speedstep now work well with no slowdown after sleep.
I have an E6400 with Nvidia Quadro NVS 160M, Core 2 Duo P8700. Sleep works with the SleepEnabler kext. However, after the sleep cycle the system is about 70% slower. The SunSpider javascript benchmark is 270ms on freshly booted system and about 400ms after the sleep cycle.

What could be causing the slowness after sleep?
Thanks!
