I can't answer this for the general case, but I do know that routers have
been doing SLARP on serial lines to acquire IP addresses "since ever"...

Given that the most current IOS versions tend to have web-based config
on-by-default, it wouldn't surprise me to see DHCP requests.

But for a definite answer, I'd just sniff the packets on the router's
ethernet ports while booting...
