I isolated my problem to a corrupt /sbin/modprobe

Here's the general instructions (since we're all here to learn) but
I don't remember the exact package name:

 # rpm -q --whatprovides /sbin/modprobe
 # rpm -V modutils

which showed /sbin/modprobe with a corrupt md5 signature.

and fixed it by reinstalling the package
 # rpm -U --replacepkgs ${install_media_path}/modutils*.i386.rpm

But that doesn't explain how it got corrupted? Now I'm interested...

However, it'll have to wait until tonight.
