Solving DNS Lag Issue - Gutsy

So after upgrading to Gutsy, I noticed that there was lag when doing a
domain lookup. I know this has been documented elsewhere, but bear with me.
I noticed that it's vastly improved when I remove the IP address for my
wireless router from /etc/resolv.conf - but I don't know how to set DHCP not
to put in that IP address when negotiating an IP address. Unfortunately, my
router is pretty braindead, so I can't set it from the dhcpd end, either.
This never happened with Feisty - I'm assuming this is related to the IPv6
issue that has been discussed elsewhere?

To get a visual of the difference between the 2 scenarios, see this
screenshot, where I got HQ to show the difference in lag times when pinging
a host:
