But with the Fedora 15 Live CD you'd be using the open source drivers - GNOME shell works fine with those, last time I tried. (I had Fedora 15 installed for awhile but had all kinds of pain with broken packages, system settings, etc.) It's a bit of a hassle to get fglrx drivers installed on Fedora so it's unlikely you were using them on the Live CD, unless I'm missing something.
