You can now validate for WGA downloads using wine and the Microsoft WGA validation tool, and you'll get a thank you message from Microsoft for using Microsoft genuine downloads. Also the anti wine checks appear to be disabled as the tool works in both windows 2000 and windows 98 mode, however the wine registry key string is still in the binary, maybe it's just disabled. In any case some EU officials have already expressed an interest in these checks, so if they enable them someone may end up getting another super fine.
