Fedora fc15 i686 NetworkManager fails after update

So I just had the unfortunate experience of a Fedora 15 update breaking the NetworkManager... which is one of the worst services to break because you're stuck finding a different PC to get on the net to find an answer.

Here is the fix:
If possible, hopefully you can 'plug in' and run dhclient em1 to get wired network access.

yum downgrade NetworkManager NetworkManager-glib NetworkManager-gnome

If you want to 'block' this update then edit /etc/yum.repos.d/fedora-updates.repo and add the following at the end of the [updates] section:

exclude=NetworkManager-0.8.999-3.git20110526.fc15 NetworkManager-glib-0.8.999-3.git20110526.fc15 NetworkManager-gnome-0.8.999-3.git20110526.fc15

Also, please head over and review/comment on the Fedora Bug report: https://bugzilla.redhat.com/show_bug.cgi?id=708445#c21
