Yeah in my original mail I said that was the solution (runlevel 1 then
update again using pam rpms from yum's cache).

What log files should I be looking at to see what caused this? I had a
look at a few but didn't see anything really obviously wrong. I don't
know if there's a way to roll-back all the updates and try again
without a whole lot of work, and I don't even know if the problem
would show itself again with certainty.

I will have a look at the rpm.spec too because something like this
should really be an atomic operation. It shouldn't remove the old
libpam.so until it's sure the new libpam.so is properly installed.
