Unfortunately, as far as I know, the Microsoft Loopback Adapter doesn't support packet capture. You'd have to ask the WinPcap developers: http://winpcap.polito.it/contact.htm about that, however - Ethereal's capturing is done, on UNIX by libpcap and by the OS mechanism libpcap uses, and on Windows by WinPcap and the OS mechanisms WinPcap uses, so that's the code that controls on what interfaces packets can be captured.
