Please tag kernel-2.6.31.5-122.fc12 - http://koji.fedoraproject.org/koji/buildinfo?buildID=139823 - for F12 Final. This fixes:

https://bugzilla.redhat.com/show_bug.cgi?id=531825 - AGP radeons fail to resume from suspend
https://bugzilla.redhat.com/show_bug.cgi?id=529292 - X dies on multiple nouveau systems

well, we hope it does. It fixes Radeon suspend for one tester; not for another, but no regression. It's fixed the nouveau protection faults for two out of four testers; the others have not yet been able to test.
