Ben & Orion - just an FYI... I can recreate this on a stock F12, or F12 with rawhide kernel (both x86_64). Running with KMS enabled, kernel 2.6.32 (git) and nouveau (git) nouveau is no longer exhibiting these symptoms. -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers
If nouveau git is working fine, you should be able to update to kernel-2.6.31.6-163.fc12 (http://koji.fedoraproject.org/koji/buildinfo?buildID=144550) and see the same results. It's identical to nouveau git, minus DisplayPort.
I still saw corruption with 2.6.31.9-174.fc12.i686.PAE and xorg-x11-drv-nouveau-0.0.15-18.20091105gite1c2efd.fc12.i686.
Updated to latest updates testing and 2.6.32.3-24.fc12.i686.PAE from koji and so far so good.
