1 is wrong,
2 is right (or at least it's a bad thing to use forced speed for 1GBit NICs )

You might want to ask your source what their source is for the first statement. We have many customers running gigabit interfaces in bonding sets...on various versions of the OS.

The spec for gigabit network cards states that at 1G speeds, it is required that autonegotiation be enabled. Some vendors drivers will ignore any attempt to disable it at this speed.

Uli,
Yes, we support bonding of NICs running at 1 gig on Linux.
