Activation checks only for hardware changes. I dont think SP2 will alter anything in activation. Besides why not go for SP3? SP3 is out for few months now
If your current system is activated, you can make backup of activation and later restore from it. You wont have to goto activation process all over again. Here is how :
1. Copy c:\windows\system32\wpa.dbl and c:\windows\system32\wpa.bak to a disk (like cd or floppy)
2. reboot XP in Minimal Safe mode (Press F8 key during system startup and choose)
3. Overwrite the files in c:\windows\system32. Its a good idea to make a backup of existing wpa.dbl and wpa.bak before u overwrite.
4. Reboot. You are activated.
