Firstly please don't send directly to me, i am subscribed to the list.
Second, its a bit hard to fix auto-negotiation in a vendors product such
as a switch, firewall or router. The sad fact is that not all hardware
plays nice with one another and you sometimes need to set the interfaces
to prevent problems. Yes that even means Gigabit interfaces. If the
interfaces negotiated correctly you would not configure the interface to
a set speed, only when they do not detect each other correctly. Maybe
that clears things up.
