As I recall, ping the broadcast address, then "arp -a".
That's pretty much it - but it assumes (1) the device is actually using
an IP address, and (2) it's on the same subnet, otherwise ping won't
help. There's a utility called arping (like ping, but for MAC
addresses) but it won't tell you the IP address. The only other
possibility I can think of is if it uses DHCP (or more likely bootp) to
try to get an address, you could snoop on that.
