 Is it possible that the Ethernet device doesn't exist yet when udhcpc starts?

 When you start it from the command line, does it work?

 So you did the following:

ifconfig eth0 up 192.168.1.1
ping 192.168.1.2

 and you get the 'Destination address required' error?

 Does ping to the configured address work?

 When you wireshark the link, do you see anything coming out?
