I assume that this is a hardware issue of the DEC21140 chips?

What about the PA-2FE-TX and IO-2FE ethernets, built on the i82543 chips?

Is IOS clueful enough to do "the right thing" on DEC and i82543 chips
(if there is a difference)?

(Is there a way to tell IOS "hey, I am using this PA-2FE-TX board because
I need larger MTUs, but I'm not going to use the second FE port, so please
shut up and don't annoy me with needless bandwidth points warnings"?)
