This issue should be solved with the next board version GTA04A4 which 
is produced right now. This board version connects the modem directly to 
the TPS chip which contains all the sound related stuff. Therefore it 
should work without additional software if you adjust the right alsa 
switches to route the audio between modem and mic/speakers.

This is still to do. The OMAP platform is very capable of saving power 
but everything must be set up within the linux kernel. This is a 
challenging task if you didn't do this before. I'm still trying to 
understand all necessary bits to help out here.
