This site should now be served properly as application/xhtml+xml and not as text/html. Since I'm now on a proper webhost I have no excuse to do otherwise anymore. I've given up trying to get it to work in Internet Explorer as well. I've tried all kinds of mod_rewrite stuff and none works. Still, there is no excuse to be using it anymore.
I should be moving over to Lighttpd soon so perhaps I'll try again there.Oh well, keeps me entertained.
