I'm sure that google's requirement for compressed sitemaps file format is sitemap.xml.gz and not sitemap.gz as output by s9y plugin for google_sitemap.
I have got this to work by changing line 306 in serendipity_event_google_sitemap.php from:
Do you maybe have a URL on Google FAQ or specs where this is indicated?
Because many people have reported that their google sitemaps worked for them, so I'm not really sure if that would break things for others?
