Recursive DNS w/ GCI

Is anyone running their own recursive/caching DNS server on a GCI
cable modem? I do and everything was working fine until I switched
over to the new DOCSIS platform a few weeks ago (from the COM21
system). My DNS server is BIND 9.2.1 on a RH 9.0 box.... everything
was working fine until the modem swap out. Now, I can NOT get BIND to
communicate with any DNS server past the RCA modem. If I configure a
non-BIND DNS server on my intranet, it gets a successful reply back
about 50% of the time. I forward recursive DNS requests to both GCI &
ACS' servers, but I don't notice any different between the two - still
about 50% of my requests go unanswered.

Ideas on where to start troubleshooting this?
