Thanks for posting that update. I did two `preupgrade` operations to go from 13 to 14 (one bare metal, one KVM guest) and a bare-metal full install, because I was blowing away the Ultimate Windows Vista 64 partition on it. All went (surprisingly) smooth.
And all emulators are working great -- love RPMFusion for that!
I am posting an updated blog article soon on what to do to make F14's Firefox browser "just work" with Flash, Java, MP3, and Midi, if anyone is interested.
