Serial console not working in 7.2-p4 and 7.2-STABLE

hi,
put hint.uart.0.flags="0x10" in /boot/device.hints, or better, make sure
you have an updated one from /sys/i386/conf/GENERIC.hints
another thing, make sure the speed/bauds is correct, else you probably wont
see any output either
in /boot/loader.conf you need

	console="comconsole,vidconsole"
and
	comconsole_speed="115200"
to set the speed.
to get a login you will need, in /etc/ttys:
ttyu0   "/usr/libexec/getty 3wire.115200"       dialup  on secure

hope this helps
