The Config Manager stencil is available for download at: http://systemcenterforum.org/wp-content/uploads/ConfigMgr2007Stencils.zip

This isn’t an official stencil of course, but is designed to provide a level of consistency with the Operations Manager stencils (a set of these are available for download at: http://www.mcalynn.com/?s=aem). 

A full set of the OpsMgr 2007 stencils are available on the CD of the upcoming Operations Manager 2007 Unleashed book (http://tinyurl.com/27mqnm). An example of the OpsMgr stencils is shown here:
