Getting kernel messages using syslog-ng 3.x

[Phusion]

I'm in need of getting help using syslog-ng 3 on FreeBSD 8.0-RELEASE.
I'm having trouble getting kernel messages. I've made a very small
config file, and this isn't working either.

@version:3.0
source local { internal(); file("/dev/klog"); unix-dgram("/var/run/log"); };
destination all { file("/var/log/all.log"); };
log { source(local); destination(all); };

The /etc/rc.conf.local has the following options in it.

syslogd_enable="NO"
syslog_ng_enable="YES"
syslog_ng_pid="/var/run/syslog-ng.pid"

This picks up other things, but not the kernel messages. I assume it's
a small configuration issue. Using file /dev/klog works using
syslog-ng 2.x on FreeBSD 8.0, but not using syslog-ng 3.x. Let me
know. Thanks.
