My mt-daapd had some problems with the new iTunes 5. But thankfully Ron fixed the issues. Now my iTunes is able to connect with mt-daapd again :D .
The new version:
Attention: this is not the final 0.2.2. It's only a nightly build.
Install/Upgrade the RPM, edit the /etc/mt-daapd.conf to your needs (MP3-Directory), go into the Runlevel-Editor of Yast and start the Service.
The latest Version for Suse 10.0 can be found here
