I hear you. I'm not sure why there wasn't a solution for power
management until Server 2008. Seems like they didn't see a reason in

The Power settings under "Policies" are Vista-only. The Power Options
under Preferences\Control Panel Settings however are for Windows XP. If
you've already rolled out the Preferences Client Side Extension
(http://support.microsoft.com/kb/943729), you can give it a try right away.

The reason it isn't possible before Vista is for two reasons:
1. The power management settings are stored in a binary format that isn't compatible with Group Policy. This is a hang-over from the days of Windows 9x when group policy was probably a distant dream.
2. The settings are mixed across HKLM and HKCU and don't work correctly in a roamed profile environment. Again this is probably a hang over-from 9x
MS have fixed this in Vista to use simple text based settings which are compatible.
The downside of GP Preferences is that as the name implies they are only 'Preferences' which can be changed by the user and therefore cannot be enforced.
If you are looking something that will work for XP have a look at Energy Star's EZ-GPO or Data Synergy PowerMan Power Manager (http://www.datasynergy.co.uk). The former is quite basic but seems to work sometimes and the later is more advanced and adds monitoring and scheduling features which can be really useful in a large organisation.
