I assume you mean with activation? The activator cracks don't work on Office SP1 but you can get round it...
When you install SP1, the new installation replaces the file MSO.DLL.
Install Office without SP1, run each application once and choose later when prompted for activation. Close all apps and apply the crack. Copy the cracked MSO.DLL to a safe place.
Install SP1. Overwrite the "new" MSO.DLL you saved earlier.
I've attached the activator crack.
