I got good news but I unfortunately forgot to blog about it (it has been soooo busy the past weeks...).
Suse now is doing an official rsyslog package. With that, I think there is now a rsyslog package for almost all major distributions available. Unfortunately, some of the current distributions do not have a good one, but it the next version will have. So over time things will be much better.
For now, let's welcome Novell/SuSe Linux to the camp of those that natively support rsyslog :)
