Casey asked for the right additional data. Additional output of the following commands might help as well:
xm list
brctl show

Double check you are plugging your cable modem to the right interface/network/VLAN.

If your modem is set into bridged mode, some ISP's requires you to clone it's MAC address on the client device, that is the VM.

Not sure about dhcp client functionality, but it's known the dhcp server does not works well unless you disable offload capability on your virtualized network card, within DomU:
"ethtool -K ETHDEV tx off" usually is enough.

Try to sniff your bridge using tcpdump on Dom0, to see what goes wrong on the DHCP negotiation.
