I have the same problem. I have a dual head Radeon X1300, and it was working well with the 8.3 driver and Gutsy. After upgrading to Hardy, I see the deadlock errors in Xorg.0.log, fglrxinfo hangs, the gnome screensaver application hangs, and locking the screen causes X to hang. I tried setting ForceMonitors to "nocv", but it didn't help. I had to disable DRI, which is less than ideal.
