For those that are interested, there are these two pages that might be useful aswell, even if the usual MOSS site statistics are not working:
http:///_layouts/usage.aspx
http:///_layouts/usageDetails.aspx
I believe these pages are provided as part of WSS, however if you install MOSS they do not appear to be linked from anywhere, as instead you get the SpUsageSite.aspx/SpUsageWeb.aspx pages with the graphs etc…
The http:///_layouts/usageDetails.aspx even shows you the total hits for the documents which are very useful information
See the following for more info:
