Hmm. During my kp49 upgrade + bridgedriver.ko rollback + brick my phone + PR1.3 kernel flash + kp49 reinstall process, the files in /lib/dsp haven't changed from the ones copied via your Harmattan instructions.

Should I roll back these /lib/dsp files as well? If these are in the libbridge2 package, I need to activate the Nokia base repos don't I?
