Most S/SC will work fine at 1.78 MHz for sound, but not for speech.   
If you are only not going to be using it for speech, just go ahead  
and assume that everyone is using it without the mod.  The funny  
thing is that the mod is to bypass a circuit used to combine the two  
clock signals to get a 1.78MHz clock.
