There is a hidden service-menu where you can set loggin up.
The service-menu is started by "dialing" this phone number:

*#*#2846579#*#*

ProjectMenu/"3. Background setting"/"2. Log setting"?

It worked after
1.) turning on logging
2.) setting log level to verbose
3.) checking options "Open Dump & Log", "Changing log switch" and "Open Sleep Log" in DumpPreferenceActivity

(maybe a restart- though settings were resetted on doing this...)
