debian/sparc serial console

[Satadru Pramanik <satadru@umich.edu>]

I've transitioned my Ultra 10 from my primary Desktop machine to  
network server (having acquired a powerbook for my primary needs  -  
still trying to get Evolution compiled on that.)  I would like to  
access this Ultra 10 only through a serial cable & ethernet, without  
monitor or keyboard.  I should be able to do this through some settings  
in Open Firmware right?

What do I need to set there, and what do I need to set inside linux so  
that it stops pestering me about no keyboard being attached.  Can I set  
these open firmware variables from inside linux?

The machine is running fine right now without monitor or keyboard  
attached - I can access it fine through ssh.

And...
How do I disable X on boot?

This page:

start
tells me that I could try this:
update-rc.d ?dm stop 99 1 2 3 4 5 6

I'm running on testing.  Would this work - I'm currently running  
debian/testing on the box?
