How are you determining that it is only running at 10-half?

I had an issue some time ago (different NIC, different driver) where I
thought that the NICs were not running at Gb speed, but it turned out
that mii-diag didn't report the correct information., but ethtool did.

I guessing from what you've said that this is *not* the problem in your
case, but thought I'd mention it.
