I can't find that one on my phone. Anyway... with these I'm able to access the usbmoden once again. Thanks so much! I wrote a script, that does the module manipulation. I will now try to cron that to run every few minutes. That is a quick and dirty solution, but should do the job. What I didn't found out yet, is how to manipulate the modem settings on the n900 through the command line. Is the selection of 2G/3G switching also done by inserting/removing modules? (@mod: should I rather open a new thread for this question, because the original one is solved?)
