Hey, Michael you should also note that (differently from before), starting with Stream SDK 1.4, AMD operated a fetch restriction on downloads. You now need to be registered. Before I used to create ebuilds for gentoo ( http://bugs.gentoo.org/show_bug.cgi?id=257626 ) to take advantage of this sdk.
Now an automated procedure is no more as easy as before.
I also look with suspect at an operation of closure on downloads to only registered people..
