My favourite method is "ping -b -c 1 <broadcast-addr>" and then look for 
the MAC address in /proc/net/arp.   There are numerous cases where it 
doesn't work, but it works often enough to be useful.   If you're using 
DHCP and you can get to the DHCP server you can also ask it about the 
mapping.

Finally, there's reverse ARP and rarpd which could be made to be useful 
if you could watch for ARP requests and use them to build up a 
/etc/ethers file.
