I noticed the same thing when I updated my PowerBook yesterday.  The 
machine wouldn't even reboot after the 'yum update' was complete; after 
'starting nash' I didn't see any output.  I had to boot from an old FC4 
CD and recover.

What I found was that glibc was apparently busted (everything 
segfaulted), along with ld.so, libk5crypto (fixing those fixed the 
'Illegal instructions' I was getting) and maybe one or two others.  I 
had to copy them from my boot image, install a new kernel and initrd, 
and reboot to downgrade to the older glibc.  I didn't see any errors 
during the upgrade either, so I'm not sure what went wrong (though the 
logs are probably still there).
