Hi Alec, I don't use that build, I roll my own so I don't know if there's anything particularly clever with it. However: I assume your clients are getting IPs via DHCP. The DHCP server on Openwrt is the truly wonderful dnsmasq. By default, dnsmasq advertises itself as the local dns server....that way it can act as a bit of a cache for dns requests AND resolve internally handled DHCP addresses for you. Dnsmasq will also do DNSSEC validation on your clients behalf too.
If you really want to hand out dns server address 'direct' to your clients and avoid all the caching/resolving goodness of dnsmasq then take a look at http://www.thekelleys.org.uk/dnsmasq/docs/dnsmasq-man.html and the '--dhcp-option' defaults. They can be overridden, indeed you can specify 'dhcp-options' via the luci gui (network-interfaces-lan-dhcp server->advanced settings' Hopefully that helps.
