Why should it care? When asking questions such as these you should use IP addresses and not names. It is less confusing to others and eliminates guesswork. Use -n in tcpdump. In your hosts file, what is the IP address for "router" and dslmodem"? Also, what is the IP address of your default route? I believe you will find that your FC2 machine is simply making a query for the MAC address of the system/device defined as the default route.
