I don't know about that. The problem is not that he can't get a link, he
is and the connection is up at 100Mb/s, but mii-tool says it's only
10Mb/s.

As for full duplex having poor support on cheaper hardware, I can easily
believe that. You don't really need (and can't really take advantage of)
full duplex in anything but a server anyway. And it would have to be a
busy one at that for you to really tell the difference.
