I found some time to do more with this. Much snipped...

Okay, I got this thing to run (sort of) at 1 Gbs. It seems that if it
ever gets started at 100 Mbs, it will never switch up, until it is
powered on with something that runs at 1 Gbs at the other end of the
wire. The "problem" is, that it won't work when both ends are running
at 1 Gbs. Usually, it just hangs, but twice it caused a TRAP 0003 in
GENMAC32. More follow up in the GENMAC list.
