Config Manager 2012 SP1 Public Beta with Linux-Clients

Hi, I'm dealing around with the public Beta of SP1 and trying to deploy rpm-packages to some SLES-Linux within my lab.
Installation andhardware inventory works fine, but I couldn't download and execute the packages. I'll just create the packages and tried to deploythem with the properties mentioned in the doc.
The policy was applied but the package wasn't dowloaded and executed. I couldn't find any mentionable errors on the scxcm.log with a hint to an error of the execmgr-component of the client.
 
Do anyone have an example xml-file of the package and deployment properties?
