  Beware though.  Autonegotiation != autodetection.  If you manually set
any duplex settings on your switch or your NIC, autonegotiation is
disabled on your switch or your NIC respectively.  Autonegotiation must be
set on both ends for it to work.  I use autonegotiation religiously now,
as I hate having to keep reprogramming switch ports.  All the hardware I
use works properly with auto.
