You won't get serial port output unless the serial port is the console.  

Try setting the OBP "intput-device" and "output-device" to "serial" and 
see if you can fire up X.  Unlike other machines, SPARCs should do 
at least some initialization of display devices even if they are not the 
console, so depending on the kernel driver.  If you can do that then 
both kernel and firmware output should go to the serial port.

Another thing to look at is turning up the "verbosity" and turning on 
"diag-switch?"  If the machine is taking a watchdog reset or otherwise 
dying in the firmware, this might turn on some output on the serial port 
even though the console is the display.

Finally, if nothing else works, you can fiddle with the kenel to swap the 
kernel cn_tab back to the serial port.
