Lost: Is this Jack?

Making a big hubbub on the "Lost" message board over the past 24 hours: Is this guy--one of the two Portuguese-speaking guys in a snowbound electromagnetic anomaly monitoring station depicted at the end of the season finale--Matthew Fox, the same actor who plays series regular Jack?

Looks a lot like him, but the part is credited to an actor named Len Cordova.

There's a nice comparison/contrast post here.
