A couple of years ago we did some research here at $WORK and found
that officially it is not a supported connection.  Something to do
with the ability of a system to see it's own data.  The very type of
thing that might cause some diagnostics to report a failure even if
the link is otherwise functional

Of course the same references (which I unfortunately don't have handy)
that say it isn't officially supported also state that it works in a
very high percentage of cases.  But no one would "guarantee" it would

I will also say that the only time I've seen a crossover cable not
work is with auto-configuring ports (like on the Netra 240).
