hello list,
here is an information what does not function on one system:
a patched drm with rnoland's patch drm-nouveau-043009.patch and a daily fresh xf86-video-nouveau causes system to freeze. there was written no coredump and no Xorg.o.log, just a freeze. the only info gotten is written to log/messages.
kernel is GENERIC with amd64. graphic card is IGP.
just for your information in wish it is helpful.

best regards

kern.ostype: FreeBSD
kern.osrelease: 8.0-BETA2
kern.osrevision: 199506
kern.osreldate: 800106
