Cool, if thats all it will take, I'll give it a try.  But, whatever
method Compaq/Intel is using doesn't require me to set up the ports on
the switch as being part of a trunk.  It "just works".  And IIRC, when
I actually tried to set the ports on the 3COM switch up as trunk
ports, it didn't work right.  Maybe 3COM is doing something entirely
different.
