boot serial console speed

[Danny Braniss]

what's the magic encantation to set the console to 38400?
btw, i solved my problem by just commenting out that part of the code,
since i rely on the bios setting it.

from src/sys/boot/i386/boot0/Makefile:

# Comm settings for boot0sio.  0xE3 => 9600 8-N-1
# XXX: We should create a build-tool or something to convert BOOT_CONSOLE_SPEED
# and BOOT_COMCONSOLE_PORT into the correct values to define on the build
# command line
BOOT_BOOT0_COMCONSOLE_SPEED?=	0xE3
