Look down at Harkernater's post 02 dec 2010. He found a good work around - as good as any we have. I've put this in that KB, but for some reason every time I look at it, the steps are missing. Maybe they'll be there for you.
Anyway, again, the release is I believe expected with ITMS 7.1 (march/april time frame currently), but I don't have a "for sure" on that yet. It might come out in a maintenance release / SP as well, but I've not heard.
