I suspect it's the latter, sshd checks if forward and reverse lookups
of clients connecting match.  How long does the latter take, do you
get the NXDOMAIN "instantaneously"?

Technically the right thing to do would be adding the hosts to your
DNS configuration.  I have an OpenWRT running dhcpd and when hosts
acquire a DNS lease with a name, OpenWRT also adds that to its
resolver, so my Wii was able to look up the connecting client in DNS.
I don't know how easy or hard it would be to incorporate something in
any way similar to your setup, but an entirely different workaround
you could try is adding the following line to /etc/hosts on your Wii:

192.168.x.5	tvpi

(obviously with the x replaced like what makes sense for your
network).

Can you give that a try and see if it helps?
