Checking your two name servers, 18.104.22.168 (google-public-dns-a.google.com) doesn't appear to offer DNSSEC validation, and 22.214.171.124 (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 126.96.36.199. 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).
