I tried the PROM console last nigth and it was a no-go. kernel downloaded
from the bootp server and just sat there, nothing on console, nothing on
serial. When I hit CTRL-C to get a prompt back, however, I discovered
that my font had changed to black-on-black, so SOMETHING happened.
This is on an Indigo2-R4400, which boots just fine over the serial
console, and CONFIG_SGI_PROM_CONSOLE asserted (after a little modification
to the config.in to take it OUT of the DEC only section, ala what Mr.
Weaver mentioned earlier, and the extraneous "NULL" removed from
setup_console in arch/mips/sgi/setup.c)
