Thanks!  When I was initially setting up bind on the SheevaPlug box
(running an ARM port of ubuntu 9.04), I'd added 20.168.192.in-addr.arpa
as a zone in /etc/bind/named.conf.local, and commented out

    // Consider adding the 1918 zones here, if they are not used in your
    // organization
    // include "/etc/bind/zones.rfc1918";

since I figured I'm using one of them.  I've uncommented the include so
it loads the zones.rfc1918 file which contains the exact approach you
describe above.  With that, and a reload of bind, I can see that what
used to go up to the UPC servers are now properly handled internally. 
At the same time, our local subnet names/addresses still resolve
correctly, which shows my initial worry which led me to commenting the
line out was a red herring.

Thanks a bunch!
