I had to put  the "hostname" the cable company (Roger's Wave) 
assigned to me into  /etc/dhclient.conf. My cable modem is attached to de0:

interface "de0" {
        send host-name "cr1000270-a";
}

Looking at the tcpdump snippet, your hostname appears to be cs840999-a. 
Running  'dhclient de0' gets me an ip address - the output is as follows:

Listening on BPF/de0/00:e0:29:0e:f7:99/unattached
Sending on   BPF/de0/00:e0:29:0e:f7:99/unattached

Note that the default /etc/dhclient-script will clobber your /etc/
resolv.conf.
