I'm doing a lot with Server 2008 lately so expect many Server 2008-centric posts for a while.
This website provides information on SPS and Windows 2008.
Their description describes the site better than I can, which is:
This page provides IT pros with resources to help deploy Windows SharePoint Services 3.0 and Microsoft Office SharePoint Server 2007 to Windows Server 2008.
As of Windows SharePoint Services 3.0 with SP1, you can install Windows SharePoint Services 3.0 and Office SharePoint Server 2007 on Windows Server 2008. You cannot install Windows SharePoint Services 3.0 or Office SharePoint Server 2007 without service packs on Windows Server 2008.
