There has to be a way (=button, =LCM) to end the call at least ;-)
Sure it's not nice to have CPU running full power for some task that can be 
done in GSM chipset (though i'm not sure this is a common feature for these 
chips. Maybe we really need a specialized chip for this), but switching off 
display is sth that can be done only while you really have the phone pressed 
to your ear - there are all kinds of user interaction (e.g. Hold, 
Mute/Volume, DTMF) and usefull info (e.g. duration, BattState) during 
established call, that need a working LCM. We have no keyboard! Just TS. 
You're not suggesting an interface-free phone you have to shake or sth to end 
the call?
However, to throttle down the CPU while call sure is a good thing, that's 
worth looking for different ways to cancel echo.
