Could you provide more information about where you're seeing this problem?
Stanford University is using, in production, the following firewall rules:

KDC:
  -A INPUT -p udp -m udp --dport 464 -j ACCEPT

Client:
  -A INPUT -p udp -m udp --sport 464 -m state --state ESTABLISHED -j ACCEPT

and it works for us, so you're running into something that I've not seen.

Maybe the problem is specific to a multihomed KDC?  That would make
logical sense to me, and if so I can certainly document that.  (Fixing it
might be another matter, although there are some patches filed upstream
for that.)
