I have had really terrible experiences trying to get support for
commodity consumer hardware. You have my sympathy.

That is what I expect to see but it does not explain why it is
offering itself as a DNS server. To me this is confirmation of the
To continue debugging this I would capture a network trace of the dhcp
transaction using 'tcpdump' and then decode it using 'ethereal'.
Ethereal has a decode module for most packet types and is a great tool
for debugging anything network related. I expect you would find
explicitly in the data packet the bad router address offerred as a dns
server. But perhaps now. Regardless it would be hard data.
I also see that 'dhcpdump' is packaged for Debian. I found it just
now by searching the package database. It looks interesting because
it is targeted and so perhaps "just the tool" for your problem. I
have never used it but it looks useful.
apt-cache show dhcpdump
Description: Parse DHCP packets from tcpdump
This package provides a tool for visualization of DHCP packets as
recorded and output by tcpdump to analyze DHCP server responses.

It is very pleasant to hear that you can forget entirely about those
other systems. That is the way that it should be. :-)
