Ah yes! Thanks for pointing me in the right direction.

Looking at my /etc/grub2.cfg I noticed that the stanza for the most
recent kernel was the same (except for kernel version) in every respect
as its predecessor - EXCEPT that it lacked the line:
initrd /boot/initramfs-3.2.7-1.fc16.i686.PAE.img

Looking in /boot I see that the following files are present: 
config-3.2.7-1.fc16.i686.PAE
System.map-3.2.7-1.fc16.i686.PAE
vmlinuz-3.2.7-1.fc16.i686.PAE

but NO initramfs-3.2.7-1.fc16.i686.PAE.img !

I have done a yum reinstall kernel-3.2.7-1.fc16.i686.PAE and I am now
speaking to you from that new kernel! 

It has however pointed up to me the fact that the last yum update did
not complete properly and there are several (about 24) other errors. I
will make that the subject of another post.

Thank you once again.
