You didn't phrase it clearly enough for me.

(Especially after 23:00)
In that case, I think I would try going into the GUI as root. Of course, in Fedora, that's not that easy, but there's a ton of different ways of how to do it around the forum.
I'd be very curious if that solves the issue. If so, it indicates (once again) that it was a foolish decision on their part to ban root login. If that doesn't solve the issue, then it's foolish of me to think it's foolish of them.
All kidding aside, you might want to clarify that on Linuxquestions as well (for others who see the thread there--that is, that there is no prompting at all for a password) If I misunderstood, there is a chance others will too. Or perhaps it's simpy due to the fact that I'm overtired and just missed it, I don't know. (As it's even later now, almost 1:00 AM)
