The best way to change where the console is going is
via the OpenBoot variables input-device and
output-device.  If these are set to keyboard & screen
respectively, and the keyboard is not plugged in, the
system will generally fall-back to using ttya as both
the input-device and output-device.  If you're really
sure you'll always want a serial console via ttya, set
{input,output}-device to ttya (you can also set to
ttyb and it will be on the other serial port, etc). 
Enjoy!
