I have to admint that I didn't really try to understand your scenarios,
but isn't it possible that syslog-ng includes a hostname in the message
while sysklogd doesn't?

When there's no hostname in the incoming message, syslog-ng adds one,
even if keep_hostname() was specified.

Check the incoming message stream with tcpdump/strace.
