I just checked the release notes, official 7.4 xorg support. I can't wait to get home tonight and try and install it! 
But hey.... Why is it that the AMD driver website (and a few other places) have very inconsistent information. This time out EVERYTHING was updated to the right version and info... except that it supports 7.4!!!
It's a good thing I miss little details sometimes too or I'd have to be mad!
