Sorry it is /etc/network/interfaces (do no post late :) )
the resolv.conf will see the line dns-nameservers rootserver and transform it
to numeric ip adress.

I can try to do this, but I am not alone to have problem with this kind of
stuff. Moreover IP are manually assigned (crappy crappy network). I am willing
to made a patch :)
If think patching /etc/network/if-up.d/000resolvconf is the way to go:
-------------
--- 000resolvconf.old 2009-08-07 12:20:57.000000000 +0200
+++ 000resolvconf 2009-08-07 12:20:46.000000000 +0200

for NS in $IF_DNS_NAMESERVERS ; do

done
echo -n "$R" | /sbin/resolvconf -a "${IFACE}.${ADDRFAM}"
---------------
This patch use only the A server, improved version that i will send you will
use A to J server
