Booting from ZFS with serial console

Hi all. I am in desperate need of some help with ZFS (maybe GPT) and
serial consoles. I use 19200 for my console speed for everything, so I
recompiled the boot blocks using "BOOT_COMCONSOLE_SPEED="19200" " in
/etc/make.conf. I then ran this to install new blocks to my two drives in
the mirror pair:
gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ad4
gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ad6
If the keyboard is plugged in when the machine starts up, all is good.
With the keyboard unplugged, I get a small error "dump" followed by "BTX
I tried this with the files from the install DVD, and the same thing
happens..."BTX Halted" without a keyboard plugged in.
In both cases, /boot.config has : "-P -S19200". I tried changing it to
"-Dh -S19200", and I get the "BTX Halted" on every boot now.
Can someone please shed some light on why it's crashing like this? I'm
fairly confident this behavior is a bug and not "by design"...but I can't
believe that this bug would not be noticed up until now.
