Cool! Adding 


to /etc/sysconfig/network-scripts/ifcfg-eth0 seems to have done the trick. Now there is a longer pause during booting when it gets to the Setting up eth0...[OK] line so I'm guessing it is waiting a little longer to get an answer from the dhcp server. 
Btw, where are the docs for the ifcfg-eth0 file syntax? There is no man page for it.
