Edimax EW-7727In nMax 300Mbps

Can anybody confirm that this will work with Win 7 RC1 x64 and Win 7 RTM x64 WITHOUT having to disable driver signing on bootup?

I used the Edimax EW-7728In when I built my brother's PC, which is basically the same as the 7727In except that it has one more antenna. It worked fine with Windows 7 RC x64. I just let Windows find its own driver for it, I didn't even bother with the CD that comes with it.
