Certainly, downgrading installations which already upgraded to faulty
packages would not work.

The situation (a broken system that cannot be upgraded) could be mitigated
a little bit by using yum + system snapshots. You can rollback to a
previous sane system.
There is a plugin yum-plugin-fs-snapshot, but it requires better
documentation and system integration.
Currently (I don't know how current is F16 documentation) it requires
running lvm by hand
