Oops....I hear my name....;) Man, AIX is like a bad flashback....it
keeps coming back to haunt me....and the memories are always painful. :)

Basically, everything that Guy wrote is right....my AIX memory
fades me. bpf under AIX is totally brain-dead and only supports
IBM's hacked and closed source version of tcpdump. Best to avoid /dev/bpf0
like the plague.
As Guy mentioned, get the latest version of libpcap from the CVS
repository at tcpdump.org, and read the README.aix file. That has
instructions I submitted for getting things to work under AIX....you
need to configure things to use DLPI. You may also need to upgrade
your bos.rte.tty fileset to the latest patch from IBM.
Once you compile libpcap, compile ethereal against that instead of the
libpcap that comes with AIX.
I've never used Token Ring under AIX, so I'm not sure how that beast will
work.
