upgrade from 5.4-STABLE -> 6 questions

[Jason]

1. after my upgrade, my serial ports are not accessible
monsterjam# ls -al /dev/cuaa*
ls: No match.
monsterjam# 

2. I get very little dmesg output after a fresh boot
monsterjam# dmesg
lpt0: switched to polled extended mode
fxp0: promiscuous mode enabled
monsterjam# 

monsterjam# uname -a
FreeBSD monsterjam.org 6.0-STABLE FreeBSD 6.0-STABLE #0: Sat Nov 19 14:21:32 EST 2005
