Yes its IPV6 that breaks it.
I disables IPV6 routing and it then works ok.

I can confirm that ntpd is broken, with the default config anyway.

I did some strace'ing and it's trying to listen on a IPv6 wildcard
address "::". 

I'm guessing it's not working because I'm not running IPv6, and I
haven't figured out if how to turn off IPv6 in ntp.conf, or if it's even
possible to turn off IPv6 in ntpd.

Anyone with some IPv6 knowledge have any ideas?  
Maybe if I activated IPv6 on eth0?  How do I do that?

For now, I guess I'll stick a 'ntpdate' in an hourly cron job to keep my
server's time correct.  But that won't help people who need to run a
real NTP server.

Yep, after reboot, and everytime I try to start xntpd.
I found another guy on the web who was complaining that he notices the same thing when running ntp
and one of the eth interfaces was down. Mine are up but that's why I rather think it's and ntp bug

as you see no port 123. Also I see no ntp in the process list

Do you get this message after you reboot the box?

What's the output of the following commands:
lsof -i tcp:123
lsof -i udp:123
