JMicron JMC250 jme interface not receiving

After getting stuck on this I left it for a couple of days while I tried
to install Ubuntu on the same machine. Then I came back to try FreeBSD
again, and it was working fine, as if by magic. I don't know what to
make of this, whether somehow the Ubuntu fiddling had an effect, or for
some other reason it settled down into a working condition. Perhaps I
had some odd problem with incorrect arp cache entries that finally timed
out. I can't really understand it.
In any event, I now see the jme driver working fine on the Eee Box B202
under both FreeBSD 7.2-RELEASE and 8.0-RELEASE.
