does anyone know of any way to prioritize DNS traffic on a Linux
server, running SLES 11? That is, to make sure that when the bandwidth
is fully used, DNS request (to an external DNS server) don't take
longer than usual? Being able to do that would make my life a whole
lot easier...
Have a look at wondershaper: a script to do traffic shaping using iptables. The idea is really to keep the connection responsive while downloading but I'd expect that to include prioritising DNS too.

As Simon suggested, DNS caching would help too.
