The system is usually always headless, so I have "-S115200 -Dh" as the sole line in /boot.config to enable a 115200 baud serial console.  This has been working fine for me up until I did a {build,install} {kernel,world} on 1st January 2013.  I was pretty sure my woes began after I did the "zpool upgrade -a" and subsequently rebooted again, but now I can't be sure whether I successfully rebooted at all after the "make installworld" and mergemaster step.

I have
root at copia:/root # more /boot.config
-Dh

and
root at copia:/root # grep 'cons' /boot/loader.conf
console="comconsole,vidconsole"
comconsole_speed="19200"
boot_multicons="yes"

Which works fine for ipmi based serial over lan console in a generic
9.1-RELEASE.
Not sure thats that helpful but 19200 is better than 9600 ;)
