dhcp client overwriting vpnc resolv.conf

[Steinar Bang <sb dod no>]

Platform: Intel Pentium M, Ubuntu dapper,
	   TrueMobile 1370 WLAN with the bcm43xx driver,
	   network-manager-gnome 0.6.2-0ubuntu7linux2go2
	   network-manager 0.6.2-0ubuntu7linux2go2
	   network-manager-vpnc 0.6.2-0ubuntu0linux2go1

I've installed the network-manager packages from linux2go, ie. the apt
line 
 deb http://www.linux2go.dk/ubuntu dapper main

They work, ie. I'm able to connect to WEP (but not WPA) networks and I
can open VPNC connections to work.

However, one problem with the VPNC support, is that the dhcp client
regularily overwrites the VPNC client's /etc/resolv.conf.

This web page https://help.ubuntu.com/community/WifiDocs/NetworkManager
seems to indicate that network manager uses BIND to do local caching
of DNS information, and presumably mediate between different sources
of DNS information (ie. the DNS server set by the DHCP client, and the
DNS server set by VPNC).

But as far as I can see with dpkg -l, I don't have BIND installed.

Is this because of the linux2go version of network-manager I
installed?  Or is the wiki in the above URL outdated?

I tried looking at http://www.gnome.org/projects/NetworkManager/
but couldn't find any documentation there.  Nor does google come up
with anything meaningful.

All pointers and references appreciated!

Thanx!
