I have had a similar experience.  After your interface starts, check to 
see if dhclient is running.  It seems that for some reason, even though I 
have BOOTPROTO=dhcp in the interface configuration file, it doesn't get an 
address, but if I run dhclient eth1 it gets an address immediately.  I 
differ in the fact that I am using encryption, and am getting my feet wet 
with wpa_supplicant .. which could be part of my issue, as encryption 
would have to be finished setting up before I could use that link to get 
an address.
