Removing "console=tty0" results in the output from the startup scripts and 
processes started from those scripts being directed to the standard tty device 
associated with ttySAC0 on the GTA01 -- resulting in this output being 
intermingled with the data intended for the GSM.  Since this is being output to 
the tty, not the console, there is no way to prevent this from inside the kernel.

So clearly this will not work for the GTA01.  Someone needs to verify that on 
the GTA02, this output will be directed to the tty associated with ttySAC2 
(which is harmless on the GTA02), and not ttySAC0 (where it will be sent to the 
GSM just like the GTA01).

[Sorry to dump this on somebody else, I'd test this myself but I don't have a 
GTA02.]
