Matches mine, and it used to get updated (but by DHCP over Ethernet 
from my local NAT box, not PPP).

Charles, if you get tired of the issue, you could, instead of solving 
it, set up a local caching nameserver (I use bind).  You might also 
need to disable updates to /etc/resolv.conf as I did (Gnome's System -> 
Administration -> Network : Devices -> Edit : DHCP Settings : 
Automatically obtain... = unchecked).  I also made mine Immutable.  
With a local nameserver, /etc/resolv.conf should either list only 
"nameserver 127.0.0.1" or it should have no nameserver entries.
