To be precise :
bind.odvr.dns-oarc.net. validates
    but seems to ignore expired (but otherwise valid) signatures.
unbound.odvr.dns-oarc.net. validates without ignoring expired signatures.

Checking your two name servers, (google-public-dns-a.google.com)
doesn't appear to offer DNSSEC validation, and
(rms.coozila.com) doesn't respond to my query at all.

A known-good publicly accessible DNSEC-validating recursive resolver is
available at bind.odvr.dns-oarc.net. If I run "dig @bind.odvr.dns-oarc.net
nox.su +dnssec", I get an AD (authenticated data) flag returned for the A
record with IPv4 address This is a prima facie indication
that DNSSEC is working for nox.su. The "+topdown" option isn't available
to me (bind 9.9.0rc2 version of dig).
