[rescue] Starting a Sun E450

[Stephen Conley]

If you haven't already tried, pull out the framebuffer and just use the 
serial console.  I have a vague memory of needing to do something 
special in openboot to get the framebuffer to be the 'boot device' 
screen, and having it in there can confuse things.

If that works, hopefully someone else here can remember the secret sauce 
to make it boot on a framebuffer because I definitely do not remember.  
If it doesn't work, well, it was low effort to try it at least :)

Good luck,

Steve
