[QUE] OMSA installation error on PE R610 (No supported system)

Hi,
I ran into some trouble installing OMSA 6.20 on a PE R610. The system is running W2k3R2, SP2. Though the pre-installation check is running fine (see warnings mentiones below), I get the message "This is not a supported Dell Server" mainly after the installation already started.
The the Rollback starts and everything ends up where it began.

The check for the system requirements reports warnings for
- Remote Enablement
- Intel(R) SNMP agent.
 
My goal actually is to configure the DRAC card in it, so that I can reach it from the outside. A reboot I'd like to avoid there. The OMSA gives me in "Remote Access" manue the option to specify an IP address and such, but this doesn't really work out.
Any hints?
