Ethereal *should* display them, but, to do so, the "get the list of 
interfaces" code would get more complicated.
Libpcap 0.7 and later have a routine that returns a list of interfaces, 
and it already has that extra stuff for Linux in it; at some point we 
should probably have Ethereal use that API if available (that'd 
probably be done at configure and compile time on UNIX; it's a bit more 
of a pain on Windows, as we'd want to do it at run time, so that 
Ethereal works with WinPcap 2.x, which lacks the API, and 3.x, which 
has it - that'd mean the Windows build of Ethereal would have to be 
compiled with 3.x, so that the appropriate data structures are defined 
in its header files).
