It turns out that its sort of related to this. I have an IPv6 tunnel
from H.E. (tunnelbroker.net) and from looking at the boot output, it
looks like the IPv6 addresses (for any of my imterfaces) aren't applied
until after pf starts. I'd say this is a bug, Oddly this didnt happen
for the release candidate I tried, although I think I may have modified
my rules and not rebooted until I upgraded.
the rules in question are:

pass in quick on $gif_if inet6 proto udp to $ext_if port $udp_services
keep state
pass in quick on $gif_if inet6 proto tcp to $ext_if port $tcp_services
(ext_if = "ue0")

I'll try changing $ext_if to the ipv6 address and see if that helps.
