Wireless DHCP overwrites DNS settings

[Jason Martens <me jasonmartens com>]

I'm still having the problem where my DNS settings are overwritten by
the wireless connection, even though I am still connected to the VPN.
Attached is the syslog output.  Note, I'm on Ubuntu Gutsy now, but I had
the same problem on Debian Lenny about 2 weeks ago.
