This may not be useful, but here's a snippet of a grub.conf (CentOS)
from a Sun V65x with Intel IPMI that works for me.
serial --unit=1 --speed=9600 --word=8 --parity=n --stop=1
terminal --timeout=5 --dumb --silent serial console
title CentOS (2.6.18-8.el5)
kernel /vmlinuz-2.6.18-8.el5 ro root=/dev/md1 norhgb quiet
That boots fine whether there's a console attached or not, but my
hardware is different enough that I don't know if that helps. And it's
been WAY too many years since I came up with that to know if I ever had
the same problem.
