I confirm it just works with wine 1.9.0, no set arch or anything else, now there are other problems with 2.4 version of the game, but is also a windows problem.
Blizzard has a habit of turning off the "Warden" that causes the problem when patches are launched. Wait a week or so, and it'll come back. You'll find that it 2.4 doesn't have the problem with 1.7, or 1.8 ether at the moment, but it'll come back as it always has.
