How many users does qemu have who need triple faults to exit from 286
Protected Mode? And how many users does it have who don't use triple
faults (yes, it's called a fault, not a PM exiting feature)
intentionally but might want the message and dumps for debugging?
Personally I suspect that a great majority belongs to the latter case.

And honestly, a message on stderr really shouldn't hurt those 286 folks.
They are even getting the reset they want from this patch.
