Well, the method that i mentioned earlier does indeed work for activation, but unfourtunately, the 'tokens.dat' method disables the important features in Windows Server 2008.
So, through intensive searching, a new method has been discovered. I have tried this myself, and it IS working for both SP1 and SP2. I'll elaborate on SP2 later on. I have uploaded these files to my file sharing account. I previously used a sharing service named ziddu, but their ads contain nothing but browser exploits. So, i changed hosts to a service called SlingFile. Good stuff.
Method #1
This method works flawlessly on Windows server 2008 service pack 1. Not only does it bypass the WPA, but it also patches the file that puts a WGA watermark on your desktop. Note that this is version 1.1, version 1 does not include the WGA gui patcher.
A NOTE ABOUT SP2:
I got a BSOD when i installed windows server sp2 and then reapplied this patch. There is a method, which uses a tool known as TimerNuke.
TimerNuke can be found here:

Keep in mind that since Method #1 allows for windows server updates, while the tokens.dat made the machine seen by windows update as vista ultimate. Therefore, after using method #1, you will recieve all updates for windows server 2008.
Service pack 2 will be listed as an update that can be installed. The user then faces two choices:
a) Keep the 'activated' version of SP1
or
b) Get the newest service pack, chick-full of security updates and such.
If you do decide to install SP2, make sure to follow the following instructions:
1. Open 'Services' in the administrative tools, and make sure the SLUI service is disabled. If this remains enabled when applying either of the tools, you will get a BSOD at every startup.
2. Run TimerNuke
3. Run Method #1
Restart.
Now, if everything goes good, you now have a Windows Server 2008 machine running SP2 that is fully updatable and does not need activation.
