Looks like I found a solution: actually I am working with a modified version of desktop activity manager - only the new scripting part. The configuration looks like the classical init-script stuff: every meta profile has it's own directory where scripts are stored that can be started and stopped (like bluetooth) and some generic scripts which use a config file for the actual meta profile (like change the real ring tone profile).

Meta profile can be changed by status menu and by script.

bluetooth, ringtone, gsm/3g are now working but I am looking for a way to change the presence states (see http://talk.maemo.org/showthread.php?p=993025). If there is some interest I will clean it up a bit and put a repo somewhere.
