Yep. 3c905B. 905C and most of the Cardbus NICs.

I don't know how useful the whole link-state-change-interrupt thing is
in practice.  The HA guys would, I suspect, say "thanks very much" and
continue to use application-level heartbeating, as they should.

We (I) need to ask them, and verify that there is actually a use for
this interface before running away and coding stuff.
