Here are three pdf files that might be of interest, I just started to read them:
* New: "Use of Open Source Software in Firms and Public Institutions: Evidence from Germany, Sweden and UK", July 2002.
Can be downloaded here:

The page is german but the files are english.
Was FSF-Europe involved in this somehow? Just curious.
