PF on NetBSD 6.0 RC1

[Edgar Rodolfo <rodolfobsd%gmail.com@localhost>]

Hi guys.
I am testing NetBSD 6.0 RC1, i saw that in NetBSD 6.0 RC1 there are
not lkm module and the file /etc/lkm.conf, I were looking for  the
file (#find / -iname lkm.conf) then i do not see the file.
I have PF currently, it works, I put in /etc/rc.conf
pf=YES
pf_rules="/etc/pf.conf"
pflogd=YES
pf_flags=""

is enough? or  should i install the module?
The documentation (http://www.netbsd.org/docs/network/pf.html) says
that to use Pf is necessary lkm, :o

Thanks in advance!
