In colo or datacenter environments ISP's and Telco's are not too  
eager about gratuitous ARPs, as they can be a sign of hacking  
activities (trying to intercept traffic to neighboring hosts or  
network devices). At any rate, the em-driver should broadcast the  
same way as bge or any of the others. I'll try to capture some ARP  
traffic on a em interface and see if it looks ok.

What would be the best way to add an alias IP without other funny  
things in the OS being triggered? Just do 'ifconfig em1 (aliasip)  
netmask (mask) bcast [bcat) alias' ?
