hm.  i'm not quite so fatalistic about it.  if a port on a hub is
labelled "uplink", it is almost certainly wired as a "nic" port and so
it takes a straight cable to a normal port on another hub.  on the
other hand, connecting two uplink ports to each other should require a
crossover cable.  (read "hub or switch" everywhere i said "hub".)

maybe a table is in order.

   one end                    other end
   ------------       --------------------------
                      NIC port       
                      uplink port      hub port

   NIC port           crossover        straight                      
   uplink port 
                                     
   hub port           straight         crossover
   switch port

better?
