The mixer settings for speakerphone, which are restored 
from /usr/share/openmoko/scenarios, have to be fixed to eliminate path from 
mic to speaker, to avoid this feedback.
Also there is a second place to look at to tweak sidetone path (that's what 
it's called, also the alsamixer settings are named in a braindead way here! 
Don't get fooled!), in modem setup. There's some AT-command to send to modem 
to stop sidetone path in modem. Mickey knows more on this.
