Spoke too soon. That one line patch makes the serial console available
early in boot. But as soon as /sbin/init runs, the console is
gibberish due to a speed mismatch. Completely reverting

http://linux.bkbits.net:8080/linux-2.5/cset@1.1653?nav=index.html|ChangeSet@-7d

works fine. Since this is a -rc kernel, can we revert the cset until
it is fixed?
