Wow. It works !!!
By patching the kext, I can boot without NullCPUPM and speed-step is enabled.
Thank you. Thank you very much.
I really appreciate your kind help.

The following is to report a result in detail.
1. Sleep :
Works. Display and HDD turn off immediately.
It takes about 2 minutes to enter S3 state totally. (Fans stop. LED blinks) - I don't know this is a normal MAC behavior or not.
2. Wake :
I can wake the system by a usb mouse, a keyboard and a power botton.
But my usb keyboard is not detected thereafter. Reconnecting is need to use the keyboard.
I think this is a problem of my old usb keyboard, because my mouse works well after wakening.
3. Sleep with Timer setting in energy saving preference.
Not work. Only display turns off.
