You could try editing your /etc/dhcp3/dhclient.conf file. There is a
line in there which specifies what the dhcp client should request, and
it includes the name servers by default. I would try removing the name
server entries and then hard coding your name servers in resolv.conf.
I've not actually tried this myself, but this is where I would start, I

I'm assuming you cannot configure your router to return more sensible
server addresses?

Does it not work at all, or does it just take a long time for your
browser to resolve the name?

I had a problem where it was taking a long time and pinned it down to
having search domains defined in resolv.conf. I removed these, and name
lookups became almost instant (you can remove the search domains from
the network configuration tool in Gnome).

I think what was happening, was the applications were appending the
whole of the search domain, letting the lookup fail, then adding part of
the search domain etc., etc., until all parts of the domain had been
used up.
