 Well, I'd love to give you some debugging output, but unfortunately we
 never got the system to panic or hang with debugging symbols. I'm not
 entirely sure what sort of info would be useful for it returning EINVAL

 As for the PHP scripts you requested, they're attached (use upload.php
 first. Since I figured it'd be useful, I also attached a sample
 lighttpd.conf.
