You could add an eth.dst and eth.src column to see the MAC header addressing in the Packet List pane.
Steps to add Ethernet Source/Destination Addresses to Packet List Pane (see note below about Wireshark v1.4.0 issue):
Click and drag your column to where you want it now and click OK. Do the same to add a Hw src addr column.
Wireshark 1.4.0 Note - One of the greatest features of Wireshark 1.4.0 is that you can right click on a field (such as the Ethernet Source Address field) and select Apply As Column. Unfortunately, using this method to create an eth.src or eth. dst column doesn't appear to work. Creating an eth.addr column does not provide name resolution. Hmmm... will have to play with it further to see if it's just me - on first cup of coffee this morning.
