Hi folks -- one thing to be careful about, I saw crazy behaviour after 
powering GSM modem on two A4s including device shutdown.  Holding the serial 
port open while trying to suspend destroyed resume as well.  Then I added a 
battery into my device, and although the GSM module remained dead on those 
A4s, the crazy behaviour went away.  So make sure to try these tests with a 
battery in if you didn't already, in case that is anything to do with it.

If there are additional "characters", they could be from some PSU noise maybe 
associated with (but evidently not triggering) the device shutdown behaviour I 
was seeing?
