lo stands for loopback. That's an internal pseudo device tied to the 127.0.0.1 (localhost) IP address.
If the wireless card is working under windows, you can type "ipconfig /all" at the command prompt, it'll return the "physical address".
I have the emachine m5310 and I wanted to try using the program from www.linuxant.com to get my broadcom wireless card to work. I need to know my mac address in order to download a key. If i use ifconfig -a it shows eth0 and lo. Eth0 is my wired nic i think. What is lo? How can I find the wireless mac address? It doesnt detect the wireless card.

The mac address is also often printed on the card
